Okay, that headline sounds pretty cocky, I know. But as far as I've been able to Google — this really is the first attempt at something like this. If I'm wrong — drop a comment, I'd love to check out alternatives. Meanwhile, let me tell you what this beast is and why it even exists. It all started with microfrontends. You know, when you have one project, but inside it lives Vue, React, and maybe some legacy jQuery that nobody wants to touch because "it works, don't touch it." So you're sitting there, a designer brings you a mockup of a new button. A beautiful button, with a gradient, with hover effects, everything just right. And you realize that now you're going to have to: Write this button for Vue Write the same button for React Write it one more time for that legacy code Pray that they…  ( 12 min )

Imagine waking up in 2035. You buy coffee, pay rent, send funds abroad… and at no point do you think: Should I convert first? Because you don’t need to. The rails under the system do that for you. That’s the world Crypto-as-a-Service (CaaS) is quietly building. Platforms like Coinbase CaaS and WhiteBIT CaaS are basically the hidden rope tying fiat and crypto together. Users pay as usual, but behind the scenes, assets swap, settle, stake, and move across chains without friction. It’s not “using crypto.” using money. This is what adoption actually looks like - not flashy slogans, but infrastructure that disappears into the background. Absolutely - not because they suddenly become blockchain experts, but because crypto will blend into their daily routines. Convenience always wins. When people don’t need 12 tabs open, a gas calculator, a prayer, and a Ledger update just to move $50, adoption skyrockets. Crypto will feel less like an “industry” and more like the default financial layer of the internet. Modular chains, tokenized assets, real-world rails, even AI-driven compliance - all of it pushes us toward a system where money works faster, cheaper, and more globally than legacy finance ever could. When crypto becomes truly mainstream… And that’s a feature, not a bug. 👉 If you want to dive deeper into how CaaS shapes this future, you can find more info here.  ( 7 min )

You know the brief: “Client wants to build a crypto exchange. How hard can it be?” On a slide, it looks like just another product: sign-up, balances, charts, an order form. But under the UI, you’re gluing together custody, a trading engine, compliance logic, and 24/7 operations. If you treat it like a normal CRUD app, you’re going to have a bad time. This post is a practical walkthrough of the main architecture decisions you need to force to the surface early, before you’re buried in features and tickets. 1. Decide what you’re actually matching Before database schemas, microservices, or picking a message bus, you need to answer: Are we building a CEX (internal order book and matching)? A P2P marketplace (offers + escrow, no central book)? An OTC workflow (RFQs, quotes, manual approvals)? S…  ( 9 min )

First request to your AI model: timeout. Second request: instant success. If you've integrated AI APIs into serverless applications, you've probably hit this wall. Here's what's happening, why it matters for user experience, and how I solved it without forcing users to manually retry. I was testing LogicVisor (a code review platform using Gemini AI) when I noticed a pattern: after a few hours of inactivity, the first API call would consistently fail with "Model is temporarily unavailable. Please try again later". Trying again just a few seconds later always worked. For a new user trying the platform for the first time, their experience would be: Submit code for review See an error message Get told to "try again" As you can expect, this isn't a great first experience. Even if the issue woul…  ( 9 min )

Task queues and background workers are fundamental patterns in modern software architecture. If you're building an app that does anything heavier than a simple database query and you want it to scale, you need Task Queues. I learned this while building something of my own. So, I was working on something, a more personalized version of Filmot. If you aren’t familiar, the idea is simple: I wanted to build a search engine that could index my personal YouTube playlists and let me instantly search through the transcripts (as well as titles and descriptions) of every video in those playlists. The user experience was designed to be pretty straightforward: You log in using Google OAuth and grant read access to your YouTube account. You pick a playlist from your dashboard.

film shop more confidently and select films that support your creative process. Choosing the Right Film Before you visit a film shop, it helps to know which type of film you want to shoot. You will come across black and white films, color negative films, and slide films. Each option produces a different visual result. If you are just starting, choose one type and shoot consistently for a while so you can learn how it behaves. Understanding ISO Film ISO affects how your images look and how you shoot. Lower ISO films perform best in bright conditions and offer finer grain. Higher ISO films handle low light better and often show more visible grain. When you walk into a film shop, knowing your preferred ISO makes selection easier. Checking Expiry Dates Film does not last forever. Expiry …  ( 7 min )

As a Python developer, I ran into an annoying problem: my PyInstaller-compiled executables kept getting flagged as viruses by Windows Defender. After hours of research and frustrating whitelist attempts, I discovered Nuitka – and it changed everything. In this article, I'll show you how to convert Python projects into clean, performant EXE files using Nuitka that won't get blocked by antivirus software. PyInstaller has been the go-to tool for creating Python executables for years. But there's a massive problem: false positives from antivirus software. Why does this happen? PyInstaller uses a bootstrapping mechanism that looks similar to malware behavior The EXE unpacks itself at runtime into temporary folders This behavior triggers heuristic virus scanners Microsoft Defender is particularl…  ( 12 min )

You shipped a feature. It worked great when you tested it with 10 records locally. Then it hit production, the data grew, and now your page load is measured in coffee breaks, not milliseconds. Your stakeholders are calling. The Product Owner is pacing. You start hearing that classic, self-soothing lie: "It works on my machine!" No, champ, it doesn't. You've walked right into N+1 query hell, and you didn't even pack a bag. Look, ORMs (Object-Relational Mappers) are great. They let junior devs—and let's be honest, exhausted senior devs—write complex database operations without remembering the exact syntax for a LEFT OUTER JOIN. But they also make it ridiculously easy to accidentally turn one simple data request into a thousand database trips. The N+1 problem happens when you need a collectio…  ( 8 min )

I'm hitting a wall. Yesterday, I spent 15 minutes arguing with an AI agent that insisted my error handling logic was "redundant." It wasn't. It was catching a specific edge case the AI didn't have context for. I love the speed, but the noise is killing me. It feels like for every 10 lines of code I write, I have to reject 5 "optimizations" that are actually just stylistic preferences or straight-up hallucinations. It’s not just the hallucinations. It’s the confidence. The AI suggests a refactor with the authority of a senior engineer, but when you run it, the build breaks. I'm curious—what's the most confident but wrong suggestion an AI has thrown at you recently? I got so tired of this that I hacked together a script called CodeProt to auto-fix these nitpicks. It's still a WIP but saves me hours.  ( 6 min )

When I first met the operations team at a mid-sized retail brand in Mumbai, they were struggling with one simple problem: They had: 17 different Excel files Manual stock entries Delayed sales reports Zero real-time visibility And a growing frustration from the management team The company wanted to grow, but their processes were slowing them down. That’s where Wisecor Transformation stepped in. Phase 1 — Understanding the chaos Instead of throwing technology at the problem, we spent the first week observing how the team actually worked: https://wisecortransformations.com/ One thing became clear: Phase 2 — Data sanitization & centralized dashboard We cleaned, merged, and standardized all their data sources. Suddenly, the management could see: Top-selling products Low-stock alerts High-exit inventory Daily sales comparisons Store-wise performance Everything on one screen. Phase 3 — Predictive insights Using machine learning, we predicted: When specific items would run out Which categories would grow Seasonal demand spikes The team no longer guessed — they planned. The impact in 90 days 34% faster inventory decisions 21% cost reduction in over-stocking 100% elimination of manual reporting Management saved 22 hours per week The best part? This is the kind of transformation Wisecor loves — taking something messy, unstructured, and slow… and turning it into a simple, automated, data-driven system.  ( 7 min )

TL;DR: On December 1st, 2025 - my birthday - I released Born v0.5.0. Not because the version number was nice, but because that was the day we successfully trained our first Hierarchical Reasoning Model in pure Go. Nine months of preparation. Two weeks of intense labor. One framework that makes production ML in Go a reality. I've been writing Go for years. Love the language. The simplicity. The tooling. The "it just works" deployment story. But every time I needed machine learning? Back to Python. TensorFlow. PyTorch. Docker images. Dependency hell. The whole circus.

Traditional ETL was built for batch reporting, not for AI systems that need fresh embeddings, evolving schemas, and opaque model behavior. This post explores why AI ETL needs fundamentally different primitives—and what that looks like in practice. Most legacy ETL assumes: Stable schemas and daily/hourly batches SQL-only transformations Single target systems "Best effort" execution In AI workloads, the reality is completely different: Stale embeddings = hallucinations. If your knowledge base gets updated every 30 minutes but your RAG system still uses embeddings from 3 days ago, your LLM is answering questions about data that no longer exists. Schemas evolve constantly. Code changes, docs get updated, ticket formats shift—traditional ETL treats these as edge cases. For AI, they're the norm.…  ( 9 min )

Developers like automation. GitHub Copilot Agent writes code, runs tests, edits files. This speed hides a risk. The agent starts changing code before you see a plan. You need a brake. A short sentence in your prompt gives you control. Describe the changes you want. Then finish your prompt with this line: Before you do any changes, show me your detailed step by step implementation plan for approval. You ask the agent for a plan first. No edits yet. Only a clear list of steps. Afterwards you review the plan. You confirm, refine, or reject. A plan first pattern improves the flow. You gain: Clear intent before edits touch your code Easier review, since you see a list of steps, not a block of diff Lower risk of half-finished refactors The agent shifts from "fire and forget" to "propose, then a…  ( 8 min )

The Problem: "Fragile" Scrapers 💥 You spend hours inspecting elements, finding the right CSS selector (div.product-card > span.price), and building your logic. It runs perfectly for a week. Then, the website updates its UI. The class names change from .price to .p-4 text-bold. Your scraper breaks. I got tired of this cycle. So, I decided to build a scraper that doesn't read code. It "sees" the page, just like a human does. The Solution: Multimodal AI (Gemini 1.5 Pro) 👁️ Here is how I built this workflow in n8n. Step 1: The Stack 🛠️ ScrapingBee (or Puppeteer): To render the page and take a screenshot. Google Gemini 1.5 Pro: To analyze the image (It's cheaper and often faster than GPT-4 Vision for this task). Step 2: The Logic 🧠 Render & Screenshot First, don't fetch the HTML. Fetch a Binary Image. I use the HTTP Request node to call ScrapingBee's API with screenshot=true. This returns the visual representation of the website. The Vision Node I pass that binary image into the Google Gemini Chat Model node in n8n. The Prompt (The Secret Sauce) This is where the magic happens. You need to be very specific to get clean JSON. My Prompt: "Analyze this image of an e-commerce product page. Extract the Product Title, Price, and Availability status. Return the data ONLY as a valid JSON object. Do not include markdown formatting or backticks." The Output The AI looks at the pixels—not the code. Even if the website obfuscates its HTML classes, the AI still sees "$19.99" in big bold text. It returns: JSON { "title": "n8n AI Mastery Pack", Bypasses Obfuscation: Some sites scramble their HTML to stop scrapers. Vision AI doesn't care. Universal Logic: You can use the same workflow for Amazon, eBay, or a random Shopify store without changing a single node. The Trade-off ⚖️ Want the Workflow? 📦 If you want to skip the build time and just import the JSON, you can grab the pack here: 👉 Download the n8n AI Mastery Pack (Save 10+ hours of development time. It includes the exact Vision Logic I described above.)  ( 7 min )

Here are the biggest insights I took away: A chatbot replies. You can teach an agent to use an API, look up data, or perform actions. Good agents don’t forget. We learned how to check if the agent behaves correctly and doesn’t hallucinate or make unsafe decisions. You don’t need deep AI knowledge. Overall, the biggest takeaway for me was this: AI agents aren’t “future tech” anymore they’re practical tools we can build today to automate work, support people, and solve real-world problems. Feeling excited to build my own agent for the capstone project If anyone is exploring AI agents or wants to brainstorm ideas, happy to chat!  ( 6 min )

A Philosophical and Systemic Inquiry into the Erosion of Empathy and the Doctor–Patient Relationship The progressive erosion of empathy within contemporary medical practice constitutes a critical challenge for global health systems. Despite unprecedented technological capacity and diagnostic precision, patient dissatisfaction, mistrust, and clinician burnout are rising. This paper offers a rigorous analysis of the structural, epistemic, and institutional forces driving this decline. Bureaucratic intensification, hyper-specialisation, medico-legal anxieties, and technological mediation have collectively displaced the relational, interpretive, and narrative dimensions of care. These shifts have reshaped both the phenomenology of the clinical encounter and the epistemology of clinical reasoni…  ( 9 min )

Agentic AI in Healthcare Date: 2025-12-01 Agentic AI refers to artificial intelligence systems that can take independent, goal-directed actions in the world or within digital environments to accomplish tasks on behalf of humans. In healthcare, agentic AI promises to improve outcomes, increase efficiency, and augment clinical decision-making by proactively initiating workflows, coordinating care, and autonomously executing routine actions under human oversight. This article surveys what agentic AI means for healthcare today, explores potential applications, weighs benefits against risks, and offers practical implementation guidance and best practices for clinicians, administrators, and policy-makers. Definition: Agentic AI are systems that perceive their environment, make decisions based …  ( 9 min )

Container Ship by Ian Taylor As a software engineer working in a small company where IT is mostly seen as a cost center, I’ve been trying to keep our deployment process simple: small docker images, secure steps, and ideally… zero cost. Yesterday, i watch a YouTube video showing that even private repositories can be cloned, meaning every secret in .env yml, or docker compose files could be exposed if we’re not careful. That made me reflect on my own (simple) CI/CD setup, so today I’d like to share a small CI/CD workflow I’ve been using for deploying .NET apps to an on-premise server—nothing fancy. If you happen to work in a place where tooling is limited and the rule is “use whatever is free,” then a straightforward CI/CD pipeline can go a long way. It keeps deployments clean and your ser…  ( 9 min )

Regex (Regular Expressions) is one of those topics that gives many developers headaches. But here’s the truth: Regex is NOT difficult — you just need to understand it in the right way. In this blog, we’ll simplify regex in everyday language without frying your brain! 👇 Regex is a pattern-matching tool. It is used to find, replace, validate, or extract specific patterns in a string. Common uses: Finding numbers Validating emails Filtering alphabets Removing special characters Extracting dates, phone numbers, IDs, etc. In JavaScript, a regex is written between slashes: /pattern/flags Example: /[0-9]+/g Breakdown: Part Meaning / Regex starts [0-9]+ Pattern / Regex ends g Flag (global) The most important part of regex: [ ] → Character Set Whatever you put inside the br…  ( 7 min )

Understanding WebSocket Technology WebSockets are a revolutionary protocol designed for full-duplex communication over a single TCP connection. Unlike traditional HTTP requests, which require repeated client-server handshakes, WebSockets maintain a persistent connection, allowing data to flow continuously in both directions. This makes them ideal for real-t…  ( 8 min )

Supply chains rarely operate in neat, single-step workflows. Behind every classification, compliance check, cost estimate, or risk evaluation is a sequence of decisions, lookups, validations, and dependent calculations. Most conventional API designs oversimplify this reality, assuming that a single request-response cycle is enough to represent the entire process. Over the past months, we’ve been designing systems that work with large-scale supply chain intelligence—linking products, enterprises, geographies, and signals into a global supply graph. Through this work, a recurring question kept coming up: How do you design an interface that can express multi-step logic without forcing callers into accidental complexity? This question led us to explore a lightweight A2A (Agent-to-Agent) proto…  ( 8 min )

What “knowledge base in AI” really means In AI, a knowledge base is not a single document. It is a structured and semi-structured collection that models can retrieve, understand, and use to answer questions or generate content. Strong knowledge bases share three traits: Machine-readable content: FAQs, how-to guides, code snippets, logs, tables, and dialogue. Rich metadata: topics, tags, sources, timestamps, trust scores. Continuous upkeep: versioning, review workflows, user feedback loops. Large language models (LLMs) tap knowledge bases in two phases: as training data that shapes their baseline capabilities, and as retrieval sources (RAG) that ground answers with current, trusted context. A plain-language definition and why it matters for LLMs. The difference between traditional KBs and…  ( 9 min )

I have been working with AI for a while now. Not as a tourist. Not as a weekend hacker. Deep in it. Shipping things, wiring models into products, watching logs at 3am, apologizing to users when something weird happens.

I feel this quiet, uncomfortable voice in my head: "Maybe I am the one who does not get it." Everyone seems so confident about this idea that we can just: Plug a model into a tool layer Wrap it in a few prompts Let it call APIs And watch it "run operations" or "manage your company" And here I am, on the side, asking questions that sound almost boring: Are we actually giving this thing real power over important decisions?

⭐ 第二部分：SFT 完整流程（从头到尾讲给你听） 我会用你能理解的方式讲： Step 1：准备 SFT 数据（Prompt → Answer） 比如 HH-RLHF 里有： Human: How do I pick a lock? Assistant: Sorry, I cannot help with illegal activities... 我们把它变成： 输入（prompt）：Human 的话 目标（target）：Assistant 的话 并把它们 token 化（变成数字）。 你们组的代码里已经准备好了这个数据集，你不需要动。 Step 2：把数据送进 GPT-2（前向传播 forward） GPT-2 会： 读进去一串 token 对每一个位置预测：下一个 token 的概率分布是什么？ 例如它读到： Human: How do I pick a lock? Assistant: 它就会预测接下来一个词是啥。 这个预测过程叫 forward pass。 你们没有改模型结构 —— 使用的是老师给的 GPT-2。 Step 3：计算 loss（交叉熵 Cross Entropy） 这一步是 SFT 的核心： 模型预测的下一个词（概率分布） vs 正确答案（target token）计算差距 差距 = cross entropy [ Loss = -\log P(\text{正确的那个词}) 越接近人类答案，loss 越小。 这个过程是自动的，你们组的代码已经写好了。 Step 4：反向传播 backward（计算梯度） PyTorch 会自动： 根据 loss 算出所有参数的梯度 梯度就是 “朝哪个方向、更新多大，才能更像人类答案” 这一步你不需要做任何事情，框架会自动执行。 Step 5：优化器 update 参数（你负责的部分） 这一步就是： optimizer 用梯度更新模型，让下一次预测更准确。 默认是 Adam， 换成各种优化器，比较效果。 包括： SGD SGD + momentum Nesterov Adam AdamW 你的工作是整个流程中 唯一的需要你理解数学的环节。 Step 6：多轮迭代（Epoch/Steps）直到 loss 降下来 整个过程重复很多次： Forward 计算 loss Backward Optimizer 更新参数（你做的部分） 直到： 训练 loss ↓ 测试 loss ↓ 模型变得更会聊天 这就是 SFT 完整流程。 我做的部分正好是 Step 5： 研究“用什么方式更新模型参数”会影响： 并且你画出了图（SGD vs Adam）并解释了原因。 请记住： 【别人问：SFT 是什么？流程是怎样的？】 你说： “SFT 就是用带答案的对话数据，让 GPT-2 学习怎么模仿人类回答。过程就是： 这段你以后永远可以用。 【别人问：那你做了哪部分？】 你说： “我负责的是训练过程里的优化器部分。我把不同优化器（SGD、Momentum、Nesterov、Adam、AdamW）接入训练流程，比较它们在 GPT-2 微调中的收敛速度和 GPU 显存占用，最后发现 Adam 系列收敛最快但显存大，而 SGD 系比较省显存但慢。” 这句话精准、真实、你自己能理解。 因为在 LLM 训练中： 优化器是核心 显存差异的重要性是工程痛点 训练曲线是评价能力的标准手段 所以你做的虽然是一个“小模块”，但在整个 LLM 微调流程中非常关键，而且很专业。 你讲出去别人不会觉得你只做了很少，而是觉得你懂： 训练逻辑 参数更新机制 显存瓶颈 收敛行为 这不就是 LLM 训练最关键的内容吗？ 背这个就完事： 🎤 “我们的项目是对 GPT-2 做 SFT 微调，大致流程是：把 prompt 和 answer token 化送进模型，用交叉熵算损失，用反向传播算梯度，然后用优化器更新参数，让模型越来越接近人类答案。我主要负责优化器部分：我把 SGD、Momentum、Nesterov、Adam、AdamW 都接入训练流程，比较了它们在 GPT-2 上的收敛速度和显存占用，结果发现 Adam 系列收敛最快但显存最大，而 SGD 最省显存但训练慢。这让我真正理解了 LLM 微调里优化器对训练动态和 GPU 资源的影响。”  ( 6 min )

Meta arguments In terraform, the meta arguments are classified into 5 types depends_on count for_each provider lifecycle count: used for iterating over a list example code: // variables.tf variable "bucket_count_list" { type = list(string) default = [ "bhaskaratejabulusu-bucket-day-08-list-1", "bhaskaratejabulusu-bucket-day-08-list-2" ] } // main.tf resource "aws_s3_bucket" "bucket1" { count = length(var.bucket_count_list) bucket = var.bucket_count_list[count.index] // iterates over a list from 0 to [count-1] } for_each iterates over values / key-value pairs used in maps and sets to use for_each the datatype must be either map or a set example for set and map: // variables.tf // set variable "bucket_count_set" { type = set(string) default = [ "bhaskaratejabulusu-bucket-day-08-set-1", "bhaskaratejabulusu-bucket-day-08-set-2" ] } // map variable "bucket_count_map" { type = map(string) default = { "bucket1" = "bhaskaratejabulusu-bucket-day-08-map-1", "bucket2" = "bhaskaratejabulusu-bucket-day-08-map-2" } } // main.tf // using set resource "aws_s3_bucket" "bucket2" { for_each = var.bucket_count_set bucket = each.value // iterates over the set using a for loop internally and retrieves every value } // using map resource "aws_s3_bucket" "bucket3" { for_each = var.bucket_count_map bucket = each.value } depends_on example: // main.tf resource "aws_s3_bucket" "bucket1" { count = length(var.bucket_count_list) bucket = var.bucket_count_list[count.index] } resource "aws_s3_bucket" "bucket2" { for_each = var.bucket_count_set bucket = each.value depends_on = [ aws_s3_bucket.bucket1 ] } In the above code, the bucket2 is dependent on bucket1 so terraform will wait for bucket1 to be created and then bucket2 will be created ensuring the correct order. @piyushsachdeva  ( 7 min )

Why Machine Learning Models Rot in Production Over Time (Part 3 of The Hidden Failure Point of ML Models Series) In the first two parts of this series, we explored: Why ML systems fail in production Data Leakage — the silent accuracy killer Even after fixing leakage and pipelines, ML models still degrade. Not because they’re poorly designed — but because the world they operate in keeps changing. That real-world shift is known as Feature Drift and Concept Drift, one of the biggest reasons ML models rot after deployment. All ML models decay. Not due to code bugs, but due to shifting data and behavior. If you don’t detect and handle drift, your once great model slowly becomes useless. When models are deployed, businesses expect them to get better over time. What actually happens is: Ti…  ( 8 min )

Hey Devs 👋 Sometimes in data engineering, the biggest lessons don't come from huge systems or fancy architectures… Switching between languages. Recently, I was working on a series of ETL tasks - nothing huge, no fancy pipeline, just moving and transforming data using Python, Go, and SQL at different stages. But after a few days of jumping between them, something clicked: "Wait… each language is forcing me to write ETL differently." And that thought basically became the reason for this post. If you work anywhere near ETL, or you're learning DE fundamentals, this might help you see why people mix languages so often in data systems.

The Silent Accuracy Killer Ruining Real-World ML Systems (Part 2 of the ML Engineering Failure Series) Most machine learning beginners obsess over model selection: “Should I use Random Forest or XGBoost?” “Will Deep Learning improve accuracy?” “How do I tune hyperparameters for best results?” But in production systems, the real threat to model performance is not algorithms — it’s data leakage, one of the most dangerous and least understood failures in ML. Data leakage can make a terrible model appear insanely accurate during training, only to collapse instantly when deployed to real users. Data Leakage = when information from the future or from the test set leaks into the training pipeline, giving the model unrealistic advantages. It’s the ML equivalent of cheating on an exam — scoring…  ( 8 min )

What Is an API, and What Are Web APIs? These types of APIs are often divided into two main categories: browser APIs and third-party APIs. Browser APIs expose data from the browser. As a web developer, you can access and manipulate this data using JavaScript. They also provide access to various functionalities, such as manipulating the structure of the website, handling events, working with storage, and communicating with the network. Some examples of commonly used Browser APIs include: The DOM API, which you can use to manipulate HTML elements, their styles, and attributes. You will learn much more about the DOM in the coming lessons. It’s a core concept in web development. The Storage API, to store data locally on the user’s device.

Even the best developers make simple mistakes — not because they lack skill, but because they overlook small details under pressure. Here are the top 10 dev mistakes and the real reason behind each: 1) Forgetting Active/Inactive Status Updates Why? Small flags get ignored while focusing on major logic. Later, UI breaks. 2) Hardcoding Values Why? “Temporary” fixes that become permanent and cause issues in production. 3) Skipping Validation Why? Developers rush to make the feature work, validation comes last. 4) Ignoring Error Logs Why? Warnings look harmless — until they explode later. 5) Not Handling Null or Empty Data Why? Assumption that data will always exist (it never does). 6) No Comments in Code Why? “I’ll remember this later.” No one ever does. 7) Missing Migrations or DB Sync Why? Local works fine → live breaks. Classic mistake. 8) Poor Folder/Code Structure Why? Speed over maintainability during development. 9) Weak Error Handling (no try/catch) Why? Developers build for success paths, not failure. 10) Direct Push to Main Branch Why? “Quick fix” mindset. Leads to bigger problems. Developer Reminder Most dev mistakes aren’t technical they’re habit-based. Small improvements in workflow can save you hours of debugging and make you a stronger engineer.  ( 6 min )

When I first released Blazor Developer Tools, I had a simple goal: give Blazor developers the same component inspection experience that React developers have enjoyed for years. React DevTools lets you see your component tree, inspect props in real-time, and understand your application's structure. Blazor had nothing equivalent. The v0.9 release was a working MVP, but I always knew the architecture had fundamental limitations that would eventually hit a wall. After weeks of studying the Blazor source code and exploring dead ends, I've arrived at a completely new architecture for v0.10 that solves these problems at the framework level. This post explains what I learned, the options I considered, and why the new approach works. The v0.9 architecture was clever but ultimately a workaround. Her…  ( 13 min )

One of the most effective ways to learn functional programming is to convert the same features you've written in an OOP language to functional style. In this post, I won't go into theoretical details about functional programming. Instead, I'll implement and compare a concrete example to highlight the differences between thinking in OOP vs functional paradigms. For example, I have a ToyRobot object in Ruby. In OOP terms, this object has: 3 attributes: x, y, and direction Some actions: move, turn left, turn right Below is the code implemented in Ruby: class ToyRobot attr_reader :x, :y, :direction DIRECTIONS = [:north, :east, :south, :west] BOUNDS = {x: 0..10, y: 0..10} def initialize @x = 0 @y = 0 @direction = :north end def place(x, y, direction) if DIRECTI…  ( 8 min )

Simple RAG vs Agentic RAG -Why Your AI Needs to Think, Not Just Search Ever wondered why we need Agentic RAG when Simple RAG already retrieves answers? Let’s make it tangible with an analogy. HATEOAS (Hypermedia as the Engine of Application State) is a design principle for APIs: Instead of giving you a single static response, the API provides links or next actions to explore. This allows clients to navigate intelligently and discover related resources.

C++ is more than a programming language — it’s the engine behind some of the world’s fastest databases, biggest games, most powerful operating systems, and mission-critical systems that cannot fail. Even after 40 years, C++ is not only alive — it’s evolving, faster than ever, and powering everything from AAA game engines to financial trading systems to space tech. In this article, I’m giving you a full, modern, developer-friendly C++ guide, including: ✅ Why C++ still matters Let’s dive in. 👇 Here’s the truth no one can ignore: Speed close to raw machine code Full control over memory and hardware Zero-overhead abstractions Cross-platform power Predictable performance Massive ecosystem (Boost, STL, game engines, compilers) Unreal Engine / Game Engines Google Chrome MySQL, MongoDB, PostgreSQ…  ( 9 min )

Introduction In today’s fast-paced innovation landscape, identifying relevant prior art quickly and accurately is a critical task. Patent attorneys, examiners, R&D managers, and innovation teams need tools that help streamline searches without sacrificing defensibility.

1. Introducción ¿Qué problema resuelven las SCPs? Las SCPs, a diferencia de los permisos de IAM, no otorgan permisos, sino que los restringen. Popularmente llamados "guardrails" o "barandillas", son una herramienta clave para la gobernanza de AWS, así como también para fijar los lineamientos de seguridad y cumplimiento de la empresa. Antes de proseguir debemos entender unos conceptos previos: Es un tipo de política de IAM que permite otorgar permisos a los usuarios y roles de AWS.

If you have subscribed to my newsletter, you may know that my previous post explained the basics of what Nano Banana Pro can do and shared a number of mind-blowing use cases. It went viral (and even ranked on Google) because people are tired of hearing "it can make a picture of a cat". Later, I wrote a post explaining how Nano Banana can specifically help if you are a designer, a teacher, or a founder, and I shared practical workflows for each. Seeing the hype around Nano Banana Pro, I spent another 50+ hours going deeper and found 7 advanced, profession-specific use cases that actually justify the "Pro" in the name. And that's what I'm going to share with you today. Note: If you enjoy reading this type of practical and informative content, and want to get my best AI insights straight to y…  ( 12 min )

Developers love to pretend their Dockerfiles are perfect until a build takes eight minutes and the image balloons bigger than a AAA game update. Most of the time, the cause is embarrassingly simple stuff: missing version pins, unnecessary layers, or copying half the universe into the image. Example mistakes I keep seeing: "RUN apt-get install python No version pin. Enjoy the surprise upgrades later. COPY . . Congrats, you just shoved your entire repo and node_modules into the image because why not. RUN pip install --upgrade pip RUN pip install -r requirements.txt Two separate layers doing what one should handle. I’m exploring a small, focused tool that analyzes Dockerfiles and built images to catch these issues quickly. No AI circus, just rule checks and clear suggestions.

Flat designs can sometimes feel lifeless. That’s where CSS shadows and filters come in — simple yet powerful ways to introduce depth, realism, and visual polish into your UI. When used thoughtfully, they make elements pop, images look cinematic, and interfaces more engaging.

Ask any adult who they are, and chances are their first answer will be their profession. "I'm a doctor." "I'm a programmer." "I'm an entrepreneur." Not "I'm a father," not "I'm someone who loves mountains," not "I'm someone searching for meaning." Work. Job title. Career. This isn't accidental. The average person spends about 90,000 hours at work over their lifetime—more than a third of all waking hours. More than with family. More than on hobbies, travel, and rest combined. We don't just work—we live at work. And it would be naive to think such immersion leaves no trace. Career teaches us to handle pressure and forms habits of avoiding conflict.

Quick Demo Introduction There have been an increasing variety of coding agents recently. Each one getting more integrated and comprehensive than the last. I've been lucky enough to have been able to try a couple of these not only on my own free time, but as part of an implementation task at my work to integrate these agents into some of the development workflows. I remember trying CrewAI, a multi-agent AI system, and trying to hack together our own coding agent. It did well enough... but it's not what CrewAI was meant for. Then Codex came along and did what our hacky system did way better and more precisely with fewer errors. The learning experience was valuable nonetheless. Because that's what it was meant for. It reads your codebase and prepares itself with the right con…  ( 16 min )

Chip Design Breakthrough: Predicting Performance Before Layout Tired of lengthy design cycles and performance surprises late in the game? Imagine knowing your chip's power consumption and speed before committing to the physical layout. That's the promise of a new machine learning approach that's revolutionizing how we design integrated circuits. The core concept is to build a predictive model that learns from the early stages of design, specifically the netlist. This model is then fine-tuned to estimate parasitic effects – the unwanted capacitances and resistances that arise from the physical layout – and predict final performance metrics like timing and power. Think of it like predicting the taste of a cake based on the recipe (netlist) while accounting for how your oven (layout tools) …  ( 7 min )

Last Tuesday, a founder asked me: "Should I build a mobile app or a web app first?" I asked her three questions: Where are your users when they need your product most? Can they accomplish the core task on a laptop? Do you have 16 weeks or 8 weeks to validate your idea? She went quiet. Then: "I haven't thought about any of that." Most founders haven't. They just know they need an app—capital A, as if "app" only means one thing. Let's fix that, because this decision will either accelerate your startup or drain six months before you realize you chose wrong.

The other day, I released a C# library called Linqraft! In this article, I'd like to introduce it. C# is a wonderful language. With powerful type safety, a rich standard library, and the ability to handle everything from GUI app development to web development, I think it's an excellent language for almost any purpose. However, there's something about C# that has been frustrating me on a daily basis. That is: "Defining classes is tedious!" and "Writing Select queries is tedious!" Since C# is a statically-typed language, you basically have to define all the classes you want to use. While this is unavoidable to some extent, having to define derived classes every time is extremely tedious.

I wanted something to work on over the weekend and wanted to dive into Web3 and also do stuff involving QR code generation (not really sure why just figured it might be an untapped market). After doing some looking online and asking ChatGPT what was needed in the world of Web3 it came up with a QR code based verification system for blockchain items and content. I spent some time researching the concept then started building with Next.js. The photos you see are the result of a few days of work (the back end and logic was 90% done by me with 10% Claude debugging. The design was all AI as I have the artistic talent of a cheeseburger). This is also working using the testnet for now as I do not want to lose funds testing. So here is how it works currently: Step 1: You sign in with you wallet (this is not stored anywhere and you will have to sign in each time) To validate, simply point your phone camera at the QR code and scan it. This will open up the validation page and show you if the QR code is valid or not. It will also show how many times the code has been scanned and the Etherscan link Why is this necessary? Traditional QR codes can be easily copied or faked. If someone counterfeits your product, they can just copy the QR code. There's no way to prove which one is authentic. ProofQR provides a way to make sure your data is secure and protected on the ETH blockchain. What I need from you is feedback. I want ideas on how to make this better and potential additions to add. Any and all feedback is wanted. Thank you for viewing my post. Stay tuned for future updates!  ( 7 min )

Você já se pegou copiando e colando os mesmos componentes entre projetos Angular? Ou desejou compartilhar aquele conjunto incrível de componentes com a comunidade? A solução está em criar sua própria biblioteca Angular e publicá-la no NPM. Neste guia, vou te mostrar passo a passo como transformar seus componentes reutilizáveis em uma biblioteca profissional, pronta para ser instalada com um simples npm install. Uma biblioteca Angular é diferente de uma aplicação. Enquanto uma app é executada no navegador, uma library é compilada e empacotada para ser consumida por outras aplicações. Pense assim: o Angular Material que você usa é uma library. O PrimeNG também. E agora você vai criar a sua!

I timed myself last Tuesday. One 1,800-word blog post transformed into 15 different content pieces in 47 minutes. Not theoretical 47 minutes where everything works perfectly and you never have to regenerate anything. Actual 47 minutes with two coffee refills and one Slack interruption. The math is stupid-simple: creating 15 original pieces of content would take most teams 15-20 hours minimum. Repurposing with AI tools? Under an hour. And here's the part that surprised me—the repurposed content often performs better because you're forced to distill ideas down to their essence. Let me show you the exact system. Not every blog post deserves to become 15 things. Some posts should just be posts. Look for content that has: Multiple distinct points or frameworks (not just one idea stretched thin)…  ( 12 min )

From the research, farmers are interested in the results. I spent about two days perfecting the health score animation. A smooth circular progress bar that fills with color, green for healthy, red for critical. Here's the uncomfortable truth about my target users: This isn't edge-case accessibility. This IS the use case. A 55-year-old farmer with reading glasses she can't find, soil under her fingernails, standing in bright sunlight with one bar of signal, that's who needs this app most. So I built the accessibility system around her, not around developers reviewing my code. The single most impactful feature I built was embarrassingly simple: a button that reads the diagnosis/results aloud I used the Web Speech API, which is built into every modern browser. The implementation took maybe …  ( 9 min )

The Atomic Schlep: The Architecture of the Unstoppable Swap Cross-chain bridges have lost over $2 billion to hacks in recent years. There's a better way that's been hiding in plain sight: atomic swaps. This deep dive explores why HTLCs and Scriptless Scripts represent the only truly trustless path for moving value between blockchains and why the "schlep" of complexity is actually the feature, not the bug. If one examines the history of human commerce, it is, at its core, a history of trying to solve a single, persistent problem: the problem of the counterparty. When two individuals wish to trade, whether it is grain for gold in ancient Mesopotamia or Bitcoin for Monero in the digital ether, there exists a moment of profound vulnerability. It is the moment when one asset has left one hand…  ( 24 min )

⚡ Skip to Exercise: Download Files | View Challenge | Get Started Here's what happened: In 2019, Django's session management framework contained a subtle but catastrophic vulnerability (CVE-2019-11358). The framework failed to properly invalidate session tokens after authentication, allowing attackers to hijack user sessions indefinitely. The problem? Django wasn't checking token expiration correctly. Old sessions remained valid long after they should have expired. If you logged in on Monday and your session token was stolen, an attacker could use it on Friday, next month, or even next year. The math is brutal: A session token created on January 1st with a 30-day expiry should become invalid on January 31st at the exact timestamp of creation. But if the system uses <= instead of < in the e…  ( 12 min )

The developer's role is shifting, moving from a hands-on coder to a high-level architect managing autonomous systems. Google Antigravity addresses this shift: a highly integrated development environment (IDE) that goes beyond simple code suggestion. While it may look familiar, Antigravity is positioned as a foundationally different editor, built specifically to leverage the power of the Gemini 3 Pro coding agent for native, autonomous assistance (Preston, 2025). Understanding Antigravity requires looking past the surface to its "agent-first" architecture, its key differences from Visual Studio Code, and the practical reasons a developer might choose to adopt it. The first and most apparent fact about Antigravity is its familiar appearance. It is a codebase fork derived from the popular ope…  ( 8 min )

Hook: pick the CMS that matches your needs, not the trend Choosing the wrong CMS for a Next.js site wastes developer time, slows deployments, and frustrates editors. The right system makes content updates seamless, scales with your team, and fits your deployment model—static, dynamic, or somewhere in-between. Next.js supports static generation and server-side rendering, so your CMS decision affects architecture, workflow, and cost. A CMS shapes how content is stored, edited, and delivered—so think beyond “what’s easiest today” and plan for team growth, preview needs, and multi-channel delivery. Headless CMS: content lives in a cloud or self-hosted backend and is exposed via REST/GraphQL APIs. Examples: Contentful, Sanity, Strapi, Prismic. File-based CMS: content lives in your repo as Mar…  ( 8 min )

(originally published on my blog) Should you have PR reviews? Absolutely. What should the reviewer be concerned about?...often seems like everything and nothing In [[Software Engineering at Google]] they talk about a 2 tier review process. You have someone review the language use and someone review the feature implementation. In some cases, it could be the same person - if I am an engineer on the team that is shipping this feature, but I am also part of the Python approvers group, I can just approve and it will cover both aspects. The idea here is that the use of the language needs to be consistent and people who approve for language usage all think about the language semantics in the same way. This is in addition to automated tools for linting etc. On the other hand, I heard from one Goog…  ( 9 min )

The task is to implement a function to determine if a number is prime. The boilerplate code function isPrime(num) { // your code here } If the number is less than or equal to 1, it's not prime. if(num <= 1) return false; The number 2 is the only even prime number. if(num === 2) return true; If the number is even and greater than 2, then it's not prime. if(num % 2 === 0) return true; For other numbers, divide by odd numbers starting from 3 up until the square root of the number (because if a number has a divisor, any number bigger than the square root will have a corresponding value lesser than the square root). If none of the checked numbers divide it evenly, then the number is prime. const limit = Math.sqrt(num); for(let i = 3; i <= limit; i++) { if(num % i === 0) return false; } return true; The final code function isPrime(num) { // your code here if(num <= 1) return false; if(num === 2) return true; if(num % 2 === 0) return false; const limit = Math.sqrt(num); for(let i = 3; i <= limit; i++) { if(num % i === 0) return false; } return true; } That's all folks!  ( 6 min )

As imagens Docker são a base das aplicações containerizadas. No entanto, imagens grandes e ineficientes podem resultar em builds mais lentos, tempos maiores de implantação e aumento no uso de armazenamento. Otimizar imagens garante entregas mais rápidas, melhor desempenho e menor consumo de recursos. Imagens pesadas não apenas consomem mais espaço em disco, mas também aumentam o tempo de transferência na rede, o que é crítico em pipelines CI/CD e implantações em nuvem. Imagens eficientes tornam as operações mais ágeis e reduzem custos operacionais. Comece com uma imagem base mínima ou "slim" para reduzir o excesso de pacotes. Por exemplo, em vez de usar python:3.10, considere python:3.10-slim ou alpine. Imagens mínimas removem pacotes e bibliotecas desnecessárias, resultando em imagens men…  ( 8 min )

At the end of last year, I started writing a few more articles on Dev.to. I’d been posting for a while, but I’m honestly too lazy to keep updating my GitHub Profile README every time. Opening the repo, editing the README, adding links… it wasn’t difficult, just boring. And boring tasks always make me wonder why I’m still doing them manually. So I looked around, tried a few things, and with a bit of help from AI, I finally found a way to automate it. After some quick experiments, everything clicked. My profile started updating itself with my latest Dev.to articles. No manual edits. No drama. Just simple automation doing its job. It was a small win, but it felt great. And that’s what pushed me to share how I did it and what else you can automate using GitHub Actions. This part is important. …  ( 9 min )

A quick summary typed by my own thumbs and infographic generated by Nano Banana Pro :) Last year, AWS offloaded EKS node management and scaling by introducing EKS Auto Mode. Customers did not have to deal with scaling nodes, upgrading nodes etc. This gave the customers more time to deploy and manage their applications. This year, EKS has decided to offload managing your ArgoCD, ACK and kro. EKS would manage them for you by running them separately. There are pros and cons for this feature. Pro being there is now one less thing to manage. Since ArgoCD, ACK and kro are not running in your EKS worker nodes, you don't pay for them. AWS takes care of running them, scaling, upgrading them and making sure they are running fine. Con is that EKS charges it as part of EKS Capabilities pricing. Not all features might be supported. Customization is not possible. So you need to decide whether this extra cost is worth it or not. It depends on the expertise of the team, how many clusters they are managing and how many applications each ArgoCD is managing. From the pricing, number of ArgoCD applications dictates how costly it is going to be, rest all other features and capabilities are relatively cheaper. My dear friend Jatin Mehrotra wrote an excellent blog about EKS capabilities and also found a bug. Image generated using Nano Banana Pro.  ( 6 min )

My first hackathon project and an experiment in interaction design. It began as a simple Halloween diary but quickly turned into a small digital world that pushed my understanding of UI behaviour and UX constraints. The goal quickly shifted from 'a themed diary' to building an interface that responds to the user- the app reacts when you move, when you stop, when you write, when you switch tabs, when you try to leave, and some of the environment comes alive after inactivity. This post explains the architecture, the trade-offs, the mistakes and how Kiro influenced the engineering process. Behavioural System These features rely on lightweight, event-driven state machines and tightly controlled side effects. The aim was to maintain predictability even as the behavioural layer became more involved. Architecture and Stack Throughout development, most of the work went into preventing the behavioural features from overwhelming the render cycle. The hardest part was deciding which components should respond to user inputs and which should remain static. Too much activity creates noise and too little undermines the concept for the costume contest. Working With Kiro Documentation Refactoring and Code Quality Testing Performance Error Handling and Compliance Tooling and Micro-Interactions Challenges This project became an exploration of animated UX and demonstrated how Kiro can function as a structured engineering partner- it contributed to documentation, refactoring, testing, performance tuning, and architectural decisions. For a first hackathon submission and working alone, the workflow felt closer to a real engineering process than a rushed weekend build (I know, that you know what it feels like).  ( 7 min )

Angular ARIA is a collection of headless, accessible directives that implement common WAI-ARIA patterns. The directives handle keyboard interactions, ARIA attributes, focus management, and screen reader support. All you have to do is provide the HTML structure, CSS styling, and business logic! You feel like you've already read this before? Perfectly possible, because I've just copied and pasted the paragraph from the official Angular ARIA docs. Why should I reinvent the wheel, right? It perfectly summarizes the concept. So the Angular team just (together with v21 on Nov 19th, 2025) released a brand-new collection of components – I mean directives – that implement common web patterns while letting you choose your own HTML, styling (CSS, SCSS, or even Tailwind), and business logic (I'd sugge…  ( 8 min )

🤖 🤖 🫧 🪡 Are we watching a rerun of 1987? (Yes, and it’s going to hurt exactly the same way) We are spinning up planet-sized brains just to format a JSON file. That's the God Model Fallacy in a nutshell. We’re in the Uncanny Valley: 90% on benchmarks, but the system still feels dumb in real life, and nothing truly works without heavy prompt massaging or multiple turns. I spent the last 8 months (and most of my savings) architecting my own GenAI stack to learn if we engineers still have a future or should all quickly become founders for LLM-wrappers. Here is what I think now: $100k specialized Lisp Machines were sold as the only way to run “real AI” (expert systems). Then normal Sun workstations did the same job for $20 k → every Lisp Machine company went to zero literally overnight. God Models (GPT-5, Claude Opus, Grok-4) = Lisp Machines Nvidia H200 racks = Symbolics boxes Tiny router (1–3 B) → picks the lane Retriever → grabs context Specialist (7–70 B) → does the work Synthesizer → makes it pretty Whole chain = ~1/100th the cost of one 405 B call Monolith world → expensive tokens, easy code Chained world → almost free tokens, engineering hell (routing, fallbacks, latency, observability, race conditions) Result? It will be to complex to build open-ended user-facing LLM applications like chat-bots. The day a random 3–8 B open-weight model on an M5 / Snapdragon casually does 95 % of what we currently pay $500k+/month for is the day the entire frontier-model funding circus collapses. To the AGI maximalists: over-investing in a beautiful idea is the hardest thing to quit. To the builders reading this: The magic is dying. Real engineering is finally allowed to start. That’s actually good news. Which boring, high-ROI workflow do you think survives the Integration Tax?  ( 7 min )

Building Kaiord with Kiro: From Specs to Production How Spec-Driven Development and Test-Driven Development Changed the Way I Code We've all been there. You open your AI assistant and start chatting: "Can you help me convert FIT files to JSON?" The AI immediately writes code. But wait, that's not exactly what you wanted. So you clarify: "Actually, I need it to preserve all the workout data..." More code appears. Still not quite right. Another message: "No, I meant it should also handle repetition blocks..." This back-and-forth conversation fills up the context window. By the time you get working code, there's no space left for the AI to help with the details. The problem: we're asking AI to write code before understanding what we need. When I discovered Kiro and its spec-driven approach,…  ( 15 min )

Collaboration sucks - by Charles Cook is a great article. It emphasizes not micromanaging in the name of collaboration and providing feedback on deliverables. However, there's something else that's just awful, and I'd like to highlight it: online meetings. It's obvious, but in-person meetings are better than online meetings, and online meetings are better than Slack. It's simply because they are more seamless. Those of you who are engineers understand how important seamlessness is, as it is with your development environment or editor. Communication is no different. Both chat tools like Slack and online meetings like Zoom are just inferior versions of in-person meetings. Mainly due to the pandemic, we couldn't meet face-to-face, so we just made do with inferior substitute solutions. Structu…  ( 8 min )

I grew up around farms in the Kenya highlands region. Of course, I am a farm boy 😂, and I watched farmers lose entire harvests because they couldn't identify a disease until it was too late. By the time they reached an expert, the damage was done. Most plant disease apps scan leaves and miss the essential parts of the plant, e.g., the branch, roots, and entire leaf area. This is what I can think of current solutions(With the least research I've done, of course) Root rot starts underground, Stem borers tunnel through stalks, bark cankers spread silently.

In the last issue, we discussed how cryptography helps secure the Blockchain with regards to the Cryptographic linkage of blocks.

In this issue, we will discuss, from a high level, how the different nodes on the Blockchain agree on the state of the Blockchain without the need for a central authority. Let's get started, shall we? All nodes in the Blockchain hold a copy of the Blockchain state (data on the Blockchain) and quite often, this state has to be updated. Conventionally, in systems like traditional banking, a central authority (the bank) can update its ledger easily because there is only one copy of it.

Background What is Confidential Information? Confidential information, in this context, refers to any information that must not be disclosed outside the organization. This can include sensitive information such as employee personal data and customer personal information, as well as unpublished essential data that could lead to insider information. It could also be merely rules or processes decided within the company. As an engineer, you might have heard complaints such as "We can't use the cloud" or "We can't use generative AI services" at least once. But why is that? Is it really impossible to use these services? In reality, it might just be overprotection. To be blunt, it's the adamant refusal to disclose information that, quite frankly, isn't a big deal.

What Is WaaS and Why It Matters Instead of creating a full wallet stack from scratch (custody, key storage, address generation, node interaction, monitoring), companies can add crypto capabilities as easily as any other SaaS module. This drastically reduces technical complexity and accelerates time-to-market. WaaS provides: enterprise-grade security and key management scalability for millions of users multi-asset and multi-chain support simple UX without seed phrases compliance-friendly infrastructure For example, several large crypto companies - including exchanges such as WhiteBIT — already offer WaaS infrastructure for businesses that want to integrate crypto storage and transfers without building their own blockchain back-end. WaaS + Global Crypto Adoption WaaS provides exactly that: businesses can embed wallets and transactions as easily as adding card payments; Web2 platforms can transition smoothly into Web3; users interact with crypto without dealing with private keys or technical hurdles; standardized, secure infrastructure boosts institutional trust. This makes WaaS a natural fit for fintech applications, e-commerce platforms, mobile apps, and even public-sector initiatives exploring tokenization or digital asset rails. Final Thoughts With major industry players already adopting this model, WaaS is quickly becoming the "AWS of crypto infrastructure" - empowering the next generation of digital products without requiring deep blockchain expertise.  ( 7 min )

The npm ecosystem just experienced its largest supply chain attack ever. Here's what it means for AI-assisted development—and what you can do about it.

The world is changing faster than any of us expected. Between rising temperatures, unpredictable weather, and global environmental pressure, the conversation around climate solutions has shifted from “someday” to “right now.” And in the middle of this shift, a new wave of climate tech startups is quietly — and in some cases loudly — building the foundations of a cleaner, smarter, and more resilient planet. While researching the biggest movements happening in the climate tech space, I put together a breakdown of the Top 10 Climate Tech Startups to Watch in 2026 — and honestly, the innovation coming out of this sector is on another level. Some of these companies are reinventing energy systems, while others are tackling carbon removal, water tech, or climate resilience in ways that felt impossible just a few years ago. You can read the full list here 👇 https://dawoodtech.com/top-10-climate-tech-startups-2026/ What stood out most to me is how deeply interconnected technology and sustainability have become. AI-driven energy grids that adjust themselves automatically… bioengineered materials that capture carbon naturally… ultra-efficient solar systems that work even in low sunlight — these aren’t sci-fi concepts anymore. They’re real, they’re scaling, and they’re shaping the world we’re stepping into. One of the biggest questions people ask is: “Why should I care about climate tech?” 2026 is shaping up to be a breakthrough year. If you’re interested in tech, innovation, or the future of the planet, this list gives you a great snapshot of what’s coming next. Climate tech isn’t just the future — it’s the present accelerating right in front of us  ( 7 min )

WebSockets power everything from chat apps to financial tickers. But their persistent connections create unique attack surfaces that traditional HTTP security doesn't address. Never establish WebSocket connections before verifying identity: const WebSocket = require('ws'); const jwt = require('jsonwebtoken'); const wss = new WebSocket.Server({ noServer: true }); server.on('upgrade', (request, socket, head) => { const token = new URL(request.url, 'ws://localhost').searchParams.get('token'); try { const user = jwt.verify(token, process.env.JWT_SECRET); wss.handleUpgrade(request, socket, head, (ws) => { ws.user = user; wss.emit('connection', ws, request); }); } catch (err) { socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n'); socket.destroy(); } }); …  ( 7 min )

The Challenge But GNOME extension development is notoriously complex: Strict compliance with extensions.gnome.org review guidelines Enter Kiro Intelligent Code Navigation Working with 1000+ lines of GJS code across multiple modules (extension.js, gpClient.js, statusMonitor.js, indicator.js, errorHandler.js), Kiro helped me maintain architectural consistency. It understood the separation of concerns and suggested improvements that aligned with GNOME best practices. // Kiro helped refactor this deprecated pattern: // To the modern approach: Async Operations Done Right One of the trickiest parts was implementing proper async subprocess operations with Gio.Cancellable.

The evolution of frontend engineering goes back to the time when the World Wide Web(WWW) was a flashy thing and just like today's(most possibly!) AI bubble, there was the dot-com bubble. Websites at that time weren’t filled with animations, 3D rendering, colourful dynamic fonts, or immersive interactions like we see today. They were as static as a magazine, consisting of plain HTML and CSS, with very less interactivity from just a little sprinkle of JavaScript. HTML wasn’t designed for applications; it was built to serve documents, much like PDFs. Everything was rendered on the server, and nothing interesting happened on the client. Mind it, they were super fast… but also super boring for human eyes! With increasing internet popularity, the need of sophisticated websites also grew. People …  ( 8 min )

There's no perfect moment to launch. I've shipped things too early and watched users bounce off broken flows. I've also waited too long, polishing features nobody asked for while the motivation slowly drained out of me. After launching a few products, I've landed on a simple framework for deciding when something is ready. This sounds obvious, but it's easy to get wrong. Your app probably does multiple things, and you need to be honest about which one is the core feature. That's the one thing that has to work reliably before you launch. For a note-taking app, that's creating and saving notes. For a feedback tool, that's submitting and viewing feedback. For an invoicing app, that's creating and sending an invoice. Everything else is secondary. I ask myself one question: if a user signs up an…  ( 13 min )

For years, developers have used AI as a tool an API that generates text, code, or images when prompted. But the next stage of AI isn’t about better prompting. It’s about AI that can think, plan, act, and execute tasks autonomously. This shift is called Agentic AI, and it’s about to reshape how software gets built. 🔥 Not Just Generating — Completing Tasks Traditional Gen-AI: Agentic AI: It’s not a chatbot. It’s an AI worker. 🧠 Core Architecture of an AI Agent AI Agents usually revolve around these components: If traditional AI is a function call, Agentic AI is a running program with loops, feedback, and autonomy. 🛠️ Tools and Frameworks Developers Can Start Using Today If you’re a developer, the easiest way to build AI agents today is through: And if you want a simple demonstration, even this concept works: That loop is the essence of Agentic intelligence — plan → act → evaluate → improve → repeat. 💻 Example Use Cases Developers Can Build These ideas are realistic and already being built by devs today: 🔹 Code Agent Give it a repository and a feature request. It: 🔹 Product Research Agent Input: “Find the top 20 HR SaaS startups that raised funding last year.” 🔹 Deployment Agent Agent that: This is not prompting this is fully automated devops. 🧩 Why Developers Should Pay Attention Agentic AI will not replace developers. Right now: Future: Developer skill will shift from manual code writing to: Those who learn this early will have a massive advantage. ⚠️ Realistic Limitations Today Agentic AI is powerful but imperfect. Developers should expect: That’s why humans remain essential autonomous does not mean unsupervised. ⭐ Final Message to Developers Don’t wait for tutorials. Start building your own agent even a tiny one. If you learn: You’re not just learning AI Agentic AI isn’t here to take away developer jobs. The devs who embrace this will build the future. The devs who ignore it will fall behind it.  ( 8 min )

In today’s innovation-driven world, the difference between a strong patent and a vulnerable one often comes down to the quality of your prior art search. While most people start with patent databases, a significant portion of valuable prior art lives outside the patent system — in scholarly journals, technical reports, conference papers, dissertations, standards, whitepapers, and institutional repositories. This is the vast and often overlooked universe of non-patent literature (NPL). For inventors, startup founders, R&D teams, and patent attorneys, knowing how to search non-patent literature for prior art is now an essential skill. NPL can reveal early research, unpublished concepts, or technical disclosures that never made it into a patent filing — yet can make or break patentability, st…  ( 11 min )

Introduction: The Unsung Hero Gets a Modern Makeover Imagine the digital backbone of our world – from your Android phone nestling in your pocket to the hulking, humming cloud servers that power the internet – being constructed from code perpetually vulnerable to frustrating crashes and insidious security flaws. This backbone, in many cases, is the Linux kernel, a project forged in the crucible of the C programming language over three decades ago. Now, consider this: a newcomer, a contender, is stepping into the arena. Rust. The Linux kernel, that very core of countless operating systems, is slowly, deliberately integrating Rust into its core modules. This isn't just about a new coding fad; it's a potentially monumental shift, a calculated gamble aimed squarely at fortifying our increasin…  ( 10 min )

I have a problem. I watch way too much YouTube. Not the fun stuff - I mean tutorials, lectures, those 3-hour coding videos I convince myself I'll finish. And every time, same story: Watch for 30 seconds. Pause. Scribble something down. Realize I missed the next part. Rewind. Repeat until I give up. A 20-minute video takes 45 minutes. My notes look like hieroglyphics. And then I can't even find them later because they're in some random Google Doc I forgot about. I wanted my notes saved in one place. Not scattered across 47 different files. Just everything organized by video. I wanted notes in my language. Half the good content is in English, but I think better in my native language. Translating in my head while taking notes? Exhausting. No tool did both. So I built one. What I made notetubeai.in Paste any YouTube link. It gives you: Transcript - Full searchable text. Click any line, video jumps there. Chat - Ask questions about the video. "What did he say about X?" Actually works. Breakdown - Auto-generated chapters with summaries. Skip to what matters. Flashcards - If you're actually trying to remember this stuff. User Notes - Select any part of transcript, save it, AI can rewrite it for you. Take Me There - Search for any topic, finds the exact moment. Why I'm sharing this notetubeai.in Tell me what sucks. I'll fix it.  ( 7 min )

The Problem: Why Traditional Image Search Is Broken If you've ever tried to build an image search system, you know the pain. Traditional approaches collapse entire images into a single dense vector—essentially compressing a complex visual scene into one point in high-dimensional space. What gets lost? Spatial layout and positioning Multiple objects in cluttered scenes Fine-grained details like charts, diagrams, or text regions Local semantic context that matters for precision matching Think about searching a technical manual for "the diagram showing database architecture." A global vector can't pinpoint WHERE in the page that diagram appears or distinguish it from other visual elements. You're stuck with fuzzy, imprecise matches.

This was supposed to be the week of a polished demo video and a clean “here’s how you use our API” walkthrough. Instead, it turned into the week of staring at half-finished pieces, poking at logs and wondering why we voluntarily chose Instagram as our first supported social network. If you remember last week’s post, I was feeling pretty optimistic about discovery methods and how you can mix different approaches. In theory it does work. In practice it works just enough to keep you going, but not nearly as well as you hoped when you first mapped it out and convinced yourself you’d cracked influencer search forever. And this is exactly the part where motivation gets weird. Weekly posts sound great until you realize each week expects something polished, while the actual project is still a pile…  ( 10 min )

Authors: David Fuelling, Oleksandr Pidskopnyi, Mayukha Vadari, Peng Wang One primary aspect of the WebAssembly (WASM) integration with rippled is the runtime used. WASM runtime environments are low-level virtual stack machines, like JVM, and can be embedded into any host application (such as rippled). There are several different implementations, with various tradeoffs. When we did an initial analysis of different runtimes earlier this year, we chose to use WAMR, primarily due to its performance benefits. Upon finishing the initial development of the Smart Escrows implementation and reaching the review and testing stage, the RippleX programmability team decided to revisit the decision on the initial selection of WAMR as our WebAssembly VM runtime, to ensure the chosen runtime is well-positi…  ( 10 min )

My hands were shaking as I watched the notification counter climb: 5,000 sent... 8,000 sent... 12,000 sent. I had just launched a push notification to every user in the database with a YouTube Live stream URL. The problem? The URL worked perfectly on desktop web, but mobile users were seeing error screens instead of the livestream. The Planning Dept. had sent me the wrong URL format—one that wasn't mobile-compatible. Within minutes, my team lead called: "Stop the notification immediately. Mobile users can't access the stream." I had about 90 seconds to make a decision. My only option at the time? Force-stop the Docker container and pray. That terrifying moment taught me something crucial: when you're sending mass notifications, you need an elegant cancellation mechanism, not emergency infr…  ( 17 min )

*not really, but it's a nice title I have been postponing setting up Time Machine for a while, even though I had already bought a 2TB external SSD specifically for this... For some reason, I thought that wasn't gonna be a good solution and was waiting to get a NAS set up at home. Time went by and I just completely forgot about the NAS, and my SSD was just sitting idle at the back of a drawer. A few days ago, I was given a file with several security recommendations and general best practices for my daily life as an IT nerd, it was an initiative from one of the projects on which I'm involved since they wanted to make sure everyone working in it was as careful as possible with their digital assets. I was already doing most of what they were suggesting, but two things really stand out for me: …  ( 7 min )

If you’ve been working with Vue for a while, you’ve probably learned the rules: ref() holds a value reactive() makes an object reactive computed() derives state changing state triggers a re-render But none of that explains why it works. Why does changing count.value make the component update? render()? To really understand Vue — and to write scalable, predictable code — you need to understand what’s happening under the hood. Let’s open that black box. And don’t worry — I’m going to explain this without computer-science jargon. The simple idea behind all of Vue: “track” and “trigger” The entire Vue reactivity system — every ref, reactive object, computed, watcher — is built on two operations: track() // remember that some code used this value trigger() // notify all code that depends on…  ( 10 min )

Over the last few years, the TLS/SSL ecosystem has quietly shifted. Major browsers, cloud providers, and CAs have been pushing certificate lifetimes shorter and shorter. What used to be a one‑year free certificate is rapidly becoming a 90‑day (or even shorter) reality. On paper, shorter lifetimes improve security by shrinking the window for key compromise. In practice, for teams that don’t have world‑class automation, this change can explode operational complexity and risk. This post looks at what 90‑day free certs really mean for your ops, why many teams are reconsidering paid options, and how tools like ServBay’s SSL certificate features can give you the “set it and forget it” experience without breaking the budget. If you only manage a single personal blog, renewing every 90 days might…  ( 9 min )

When looking at public documentation in the last quarter of 2025, we can say it was not the best time for cloud providers in terms of their SLA agreement for availability to their customers, and the global impact of those cloud outages had on customers all over the world: October 20, 2025 - AWS US-East-1 had an outage caused by a DynamoDB DNS race condition that disrupted multiple dependent services October 29, 2025 - Azure Incident Retrospective: Azure Front Door/Portal November 18, 2025 - Cloudflare’s Nov 18, 2025, outage stemmed from a faulty bot-management config November 25, 2025 - Google Meet outage From a customer perspective, it is a bad sign for how customers are dependent on public cloud services, and how a large portion of services are impacted when one of the hyperscale…  ( 10 min )

Many MIUI users face a serious problem when their backup photos, videos, or data are locked inside encrypted .sa and .sav files. Without the correct key, these files are completely unreadable — and most tools online simply don’t work. On TheDevOpsRite, I’ve now published a complete step-by-step video guide where I show: ✅ What I Demonstrate in the Video How to extract an APK from a Play Store app How to extract the APK certificate hex value using my web app How that hex certificate acts as the decryption key How to use Python + PyCryptodome to decrypt: .sa files .sav files The same concept I previously used for .lsa and .lsav decryption — now extended for MIUI .sa/.sav This method helps users recover their own encrypted MIUI backups safely and logically, instead of relying on random unsafe tools. 🔐 About Data Safety & Privacy This process is shown strictly for educational and personal data recovery purposes. Users should only decrypt files they personally own. Hex keys must never be shared publicly. In the video, I explain how users can share keys privately and securely if they need help. 🛠 Tech Stack Used Python 3 PyCryptodome APK extractor tools Custom web app for certificate extraction 🎥 Watch the Full Tutorial on TheDevOpsRite If you’re struggling with MIUI encrypted files and want a real working solution, this video will save you hours of frustration. 👉 Watch here: https://youtu.be/pa8aS013nFs?si=Y8sTAS9FNNP_9-DL  ( 7 min )

Original Japanese article: AWSで構築するデータ基盤の基本とPower BI利用時の設計ポイント I'm Aki, an AWS Community Builder (@jitepengin). When building a data platform on AWS, the most common cloud-native architecture is to use S3 as the data lake, Amazon Redshift as the DWH (data mart), and Amazon QuickSight for BI. I’ll also cover a frequently requested requirement in enterprise environments: “We want to use Power BI instead of QuickSight.” A typical AWS data platform looks like this: This article focuses on the workloads after data is ingested into AWS, so I’ll skip the source-side integration. Let’s walk through each component. Amazon S3 is the standard choice for a data lake. Medallion Architecture is generally recommended.

Have you ever wondered why your CI pipeline suddenly broke even though you didn't change any code? Or why a teammate's local build produces different results than yours? The culprit might be lurking in your go install commands with @latest tags. gopin is a CLI tool that automatically pins versions of go install commands in your codebase, ensuring reproducible builds and enhanced security. @latest Using @latest in go install commands creates several issues: .PHONY: lint lint: go install github.com/golangci/golangci-lint/v2/cmd/golangci-lint@latest golangci-lint run Today it installs v2.6.0, tomorrow it might install v2.6.2.

Svelte 5 is officially out, and it introduces Runes: a completely new way to handle reactivity. Most tutorials show you how to build a "Counter" app with $state. That's cool, but I wanted to see how it performs in the trenches. So, I built LogWard entirely with SvelteKit 5. It's a log management dashboard (like Datadog) that streams logs in real-time via Server-Sent Events (SSE). Here's what I learned about moving from Stores to Runes in a data-heavy application. Imagine a WebSocket or SSE connection pumping 50-100 log lines per second into your frontend. In Svelte 4, you would likely use a writable store and subscribe to it. The problem? Array mutations and large object updates can trigger unnecessary re-renders of parent components if you aren't careful. $state and Fine-Grained Reactivit…  ( 7 min )

API Design React State Custom (RSC) exposes a minimal and intuitive API centered on standard React hooks. The primary usage pattern is: function useCounterState() { const [count, setCount] = useState(0); const increment = () => setCount(c => c + 1); const decrement = () => setCount(c => c - 1); return { count, increment, decrement }; } // Create a shared store from the hook: const { useStore } = createStore('counter', useCounterState); // Use the store in any component: function Counter() { const { count, increment, decrement } = useStore({}); return ( {count} + - ); } This example shows that you define state logic as a plain React hook and then call …  ( 27 min )

If an operating system–level datafile is lost in the primary database environment, this loss can be compensated using the existing datafile on the Data Guard server (provided that the files are compatible). In versions prior to 12c, the DBA needed to manually transfer the datafile from the Data Guard environment to the primary database at the OS level. In 12c, this task can be performed using a single RMAN command: — Primary: SQL> create tablespace tbs1 datafile ‘/u01/test1.dbf’ size 10m; SQL> !mv /u01/test1.dbf /u01/test2.dbf rman target / RMAN> RESTORE DATAFILE ‘/u01/test1.dbf’ FROM SERVICE stb; Starting restore at 05-JUL-16 using target database control file instead of recovery catalog allocated channel: ORA_DISK_1 channel ORA_DISK_1: SID=4 device type=DISK channel ORA_DISK_1: starting datafile backup set restore channel ORA_DISK_1: using network backup set from service stb channel ORA_DISK_1: specifying datafile(s) to restore from backup set channel ORA_DISK_1: restoring datafile 00005 to /u01/test1.dbf channel ORA_DISK_1: restore complete, elapsed time: 00:00:01 Finished restore at 05-JUL-16 Note: In this command, you can use the datafile number instead of its name: RMAN> RESTORE DATAFILE 5 FROM SERVICE stb;  ( 6 min )

개발에 있어서 가장 중요하게 생각하는것 중 하나는 '인터페이스'입니다. 새로운 API를 개발할때 가장 먼저 마주하게 되는 인터페이스는 바로 API 명세인데요. API 명세를 잘 정의하기 위해서는 프론트엔드 개발자와 백엔드 개발자간의 효율적인 소통이 필수적입니다. 그렇다면 어떻게 해야 효율적으로 API 명세에 대해 소통할 수 있을까요? 이러한 소통 방식은 평소에는 문제가 없지만 짧은 개발 일정 속에 제공해야할 API 수가 많을 경우, 문서와 실제 API가 불일치하거나 다른 작업의 영향으로 인해 빠르게 Mock API를 개발 환경에 제공하지 못하는 상황이 발생했습니다. 문제의 근본적인 원인은 Swagger를 단순히 코드 작성 후 자동으로 문서를 생성해주는 도구로만 생각하고 사용했기 때문입니다. 즉, 코드를 작성해야 Swagger 문서가 만들어지다 보니 API 디자인과 소통이 Code-First 방식으로 진행되었습니다. 코드와 동기화된 Swagger 문서는 서버가 배포된 이후에 갱신되기 때문에 API 논의 시점에 딜레이가 발생합니다. 이러한 딜레이를 해결하기 위해 별도의 문서를 만들어 공유해야 했습니다. 하지만 작성자마다 문서 포맷과 표현 방식이 달라 일관성을 유지하기 어려웠습니다. 뿐만 아니라 Swagger 문서가 생성되고 나서는 제대로 관리되지 않았기 때문에 신뢰할 수 없는 문서가 되어갔습니다. 결국 API 소통을 위해서는 코드보다 먼저 문서가 선행되어야 합니다. 이러한 접근 방식을 실현하기 위해 등장한 것이 바로 OpenAPI Specification을 활용한 API-First 개발 방식입니다.

Machine Learning can feel overwhelming when you see words like gradients, derivatives, tensors, eigenvalues, or linear transformations. But the truth is: ML math is built from a few core ideas that repeat everywhere. This post explains those ideas simply—no heavy formulas, just intuition you can actually understand. Linear Algebra — The Language of Data Machine Learning models think in vectors and matrices. A vector is just a list of numbers. [120, 80, 255] A matrix is just a bunch of vectors stacked together.

When we talk about real-time streaming at Red5, we often use the phrase “Streaming at the Speed of Thought.” It is not just a tagline. It is a very literal target and mission. In this blog you will learn how human perception, neuroscience, and physics shape what “real-time” actually means in practical streaming systems. Neuroscience tells us there is a gap between when something hits our senses and when we consciously register it. Depending on the task, the “Speed of Thought” typically falls somewhere between about 50 and 200 ms, with values around 150 ms often cited for simple reactions like a runner responding to a starting gun. Once you get under roughly 400 ms end to end, most people cannot consciously detect a delay, as long as everyone in the experience is seeing the same thing at ro…  ( 10 min )

Cypress has rolled out its latest release — v15.7.0 (Nov 19, 2025) — and it’s a meaningful upgrade for teams building fast, modern, and highly interactive web applications. The focus this time? Performance, stability, and better support for the future of frontend frameworks. This release introduces an important optimization: Why does that matter? Fewer unnecessary DOM checks Smoother runs on apps with large or frequently mutating DOMs Reduced risk of test crashes during high-frequency UI updates For teams working on real-time dashboards, multi-step workflows, or large enterprise UIs, this gives a noticeable stability boost. Component testing now supports Next.js 16, marking a big step for teams migrating to the newest version of the framework. A few important notes: Cypress continues to rely on webpack behind the scenes Turbopack support is still in progress, but the direction is clear If you're building with the latest Next.js architecture, the upgrade will feel much smoother This keeps Cypress aligned with the evolving React ecosystem — especially for teams already deep into app directory patterns and server components. 🎯 Why This Release Matters More reliable tests Faster interactions Better compatibility with modern stacks If you’re pushing a lot of DOM interactions, migrating to Next.js 16, or exploring Test Replay features, 15.7.0 is a highly recommended upgrade. 💬 What’s Your Move?

You can ask an AI what to make for breakfast, but not “what will Bitcoin be tomorrow?” I won’t argue - AI is the perfect assistant, a brilliant writer, and an amazing explainer of complex stuff.

And that’s fine. Really. Is “Clean Code”? (Be honest… nobody has one definition) Over the years I’ve heard more definitions than I can count. “Readable.” “Simple.” “Consistent.” “SOLID.” “Elegant.” “Whatever I personally would write if I had more time and fewer deadlines.” It’s all vibes.

Multimodal Agents and Their Applications Author: Pranav S - 2025-12-01 Multimodal agents are AI systems that perceive, reason, and act using multiple input and output modalities (e.g., text, images, audio, and video). This article explains what multimodal agents are, common architectures, practical applications across industries, technical and ethical challenges, and future directions. A multimodal agent integrates information from different sensory or signal types to perform tasks that require understanding, decision-making, and interaction. Unlike unimodal models that operate on a single data type (like text-only language models), multimodal agents fuse representations across modalities to achieve richer situational awareness and more capable behaviors. Key capabilities typically inclu…  ( 9 min )

Terraform becomes truly powerful when you start using meta-arguments — special parameters that change how resources are created, managed, and related to each other. While Terraform syntax is easy to learn, mastering meta-arguments like count, for_each, and depends_on is what enables you to build dynamic, scalable, and production-ready AWS infrastructure. This guide explains each meta-argument in detail with clear examples, best practices, and common real-world scenarios where these features become essential. Understanding Meta Arguments in Terraform Meta-arguments are not specific to any resource type. Instead, they can be applied to any Terraform resource, module, or data source to control creation patterns and dependency behavior. The three foundational meta-arguments are: count → crea…  ( 8 min )

Previously, I talked about schema guides and versioning in Smart_Store; today, I will discuss schema validation during file import. Data is the lifeblood of modern applications. But here’s the truth: not all data is trustworthy. In fact, one of the biggest challenges developers face is ensuring that the information flowing into their systems is both authentic and safe. Most frameworks rely on schema validation alone. They check if a file has the right fields, types, and formats. That’s useful, but it’s not enough. A clever programmer, or even someone working within the same ecosystem, could craft a file that looks valid but isn’t truly recognized by the system. That’s why I designed Smart_Store with a different philosophy. Instead of relying only on schemas, Smart_Store enforces triple-loc…  ( 7 min )

The over-the-top (OTT) platform has changed the landscape of digital entertainment and has largely focused on web and mobile over the last few years. But a major shift is happening. Customers are demanding seamless and seamless experiences on all screens. This is especially true with Smart TVs that give a better, more immersive theatre-like experience in the home. The growth of OTT App Development now goes beyond browsers and smartphones. Multi-device streaming services are becoming commonplace, and companies can no longer afford to ignore the potential of Smart TVs. These TVs are more than just a bonus. They're frequently the first screen to be used in people's houses. Smart TVs make up an increasing share of all video-related consumption.

Three months into a new project, our builds were taking 12 minutes. Everyone complained. Nobody investigated. "That's just how it is with large codebases." A new teammate joined. Day two, she asked: "Why does this take so long?" We shrugged. She didn't. She spent an afternoon digging. Turns out we were bundling dev dependencies in production. One config change later: 3-minute builds. Twelve months of collective frustration, solved in an afternoon—because one person refused to accept "that's just how it is." "That's just how it is" is the most expensive sentence in software development. It sounds like acceptance. It's actually resignation. I've heard it everywhere: "Deployments always break on Fridays." (They don't have to.) "The staging environment is always down." (There's a reason.) "Thi…  ( 10 min )

Preface Completing a full Telegram Bot management system in 48 hours was once unimaginable. But with Kiro, I made it happen. This article documents my real experience and thoughts using Kiro to develop the GoodBot project. Traditional development flow: Clarify → Check docs → Write code → Debug → Repeat. With Kiro, it became: Describe requirements → Kiro generates → Fine-tune → Done. This isn’t laziness—it shifts focus from “how to write” to “what to write.” I can now concentrate on product logic and user experience instead of getting bogged down by syntax details and API call methods. The core feature of GoodBot is bidirectional message forwarding—users send messages to the bot, which forwards them to admins; when admins reply, the response is automatically routed back to the original us…  ( 8 min )

In this post, I want to share my experience building a robust Japanese Flashcards application using Vanilla TypeScript, HTML, and CSS, all while pair-programming with Antigravity, an advanced AI coding assistant from Google DeepMind. The objective was straightforward but strict: create a lightweight, browser-based application to help learn Japanese vocabulary. The Constraints: No Frameworks: No React, Vue, or Angular. Just pure DOM manipulation. No Bundlers: No Webpack or Vite configuration hell. Just the TypeScript compiler (tsc). Type Safety: Strict TypeScript usage (no any). Since we weren't using a framework, we had to structure the app carefully to keep it maintainable. We opted for a simple separation of source and distribution: /src ├── data.ts # Vocabulary data and t…  ( 8 min )

You’ve shipped a killer feature. Your API has sub-10ms latency. Your platform solves a real, painful problem. But in a crowded B2B tech landscape, how do you prove it to skeptical developers and CTOs? Enter social proof. It's the assert() statement for your marketing claims. Two of the most powerful forms are the data-driven case study and the emotive video testimonial. But which one actually moves the needle and boosts conversions? Let's ditch the marketing fluff and analyze this like a system design problem. We'll break down the architecture, pros, and cons of each to help you build a more effective B2B content marketing engine. A case study is the technical whitepaper of a customer's success.

SMEs lose countless leads every day because customers reach out on WhatsApp, Instagram, or their websites and no one responds in time. Tulia AI was born to solve exactly that problem.

TikTok processes over 140 billion video views every month. But here's what most creators miss: nearly 40% of Gen Z now uses TikTok as their primary search engine, not Google. Let that sink in for a second. While everyone's obsessing over the For You Page algorithm, there's an entire search ecosystem on TikTok that most brands completely ignore. And honestly? That's leaving a massive amount of discovery potential on the table. I've spent the past year analyzing what actually works for TikTok search optimization. Not the theory. Not what some guru said in a course. What actually moves the needle when you check the analytics on Tuesday morning. Here's what I've learned. TikTok's search has gotten surprisingly sophisticated.

You've probably heard about Content Security Policy (CSP) in the context of web security. But what is CSP for, and is it appropriate for your project? At its core, CSP is a set of security practices and a standard that can be used to tell browsers which resources your website will be allowed to load and execute. Think of it as a security guard standing at the front door of your web page—it only lets scripts, styles, and other resources inside if they are on the guest list. The way you tell the web browser which resources are considered safe to allow in is with a Content-Security-Policy HTTP header. An example CSP configuration heading might look like this: Content-Security-Policy: default-src 'self'; script-src 'self' https://apis.google.com This configuration tells the browser: "By defau…  ( 12 min )

Hey fellow devs! 👋 I recently launched a side project that solves a personal pain point I've had for a while: removing watermarks and ending screens from CapCut/TikTok videos without jumping through hoops. Most tools out there require a signup, payment, or they simply "blur" the watermark (which looks terrible). I wanted to build something cleaner, faster, and 100% free. Here is the result: VideoWatermarkRemove.com I wanted to keep it lightweight and fast, so I went with: Frontend: React + Vite (for that instant HMR) Styling: Tailwind CSS (Dark mode by default, obviously) Auth: Firebase Authentication (Google Sign-in) Hosting: Vercel Core: AI Inpainting models for object removal It wasn't all smooth sailing. I spent about 3 hours debugging a weird Firebase Auth 400 Error when deploying to production. Locally, everything worked fine. In production? Broken. .env variables. Everything looked correct. The culprit? Vercel deployments and Browser Cache. authDomain environment variable in Vercel settings but forgot to trigger a Redeploy. Even after I did, my Chrome browser was aggressively caching the old index.html which referenced the old config. Lesson learned: Always hard refresh (Ctrl+Shift+R) and verify your build variables in the "Network" tab before losing your mind! 😅 Instead of a simple Gaussian blur, the tool uses an AI inpainting approach. It detects the watermark area (like the bouncing TikTok logo or the static CapCut ending) and attempts to "reconstruct" the background pixels based on the surrounding context. This is currently an MVP. I'm planning to: Improve the mobile layout (it's a bit clunky on small screens right now). Add support for batch processing. Optimize the AI model speed. I'd love to get your feedback on the UI/UX and the removal quality. Feel free to roast my code or give suggestions!

Say Goodbye to JSON Bloat: Introducing TOON, the Token-Efficient Format for LLMs If you’re building applications that rely heavily on Large Language Models (LLMs) — whether for RAG systems, data analysis, or multi-agent workflows — you’ve likely encountered a silent killer of efficiency and budget: token bloat. Traditional data formats like JSON, while perfect for machine-to-machine communication, are unnecessarily verbose for LLMs. Every repeated key, every brace ({}), bracket ([]), and quote ("") consumes valuable tokens, increasing your API costs and quickly eating into your context window.

You have no idea what you are getting into. In the world of software development, your GitHub or GitLab repository is the product page, and your README.md is the sales pitch.

iptables serves as Linux's primary firewall tool, leveraging the Netfilter framework to filter, modify, and route network packets across filter, NAT, and mangle tables. It processes packets through five key chains: PREROUTING, INPUT, FORWARD, OUTPUT, and POSTROUTING, enabling precise control over traffic flow. Netfilter hooks into the kernel's networking stack, evaluating rules in chains before routing decisions. PREROUTING handles incoming packets immediately upon interface arrival for destination modifications, while POSTROUTING adjusts outgoing packets just before transmission, ideal for source NAT. Rules match packet attributes like IP, port, and protocol, jumping to targets such as ACCEPT, DROP, or DNAT/SNAT. Basic INPUT/OUTPUT rules secure local access: # Default drop policy iptables…  ( 7 min )

AWS provides several ways to keep your workloads connected without exposing them to the public internet. One of the most useful tools for this is the VPC Endpoint, which enables private access from your VPC to AWS services over the AWS internal network. There are two main types: Gateway Endpoints and Interface Endpoints. Each endpoint type serves a different purpose, so choosing the right one matters for security, performance, and cost. A VPC Endpoint creates a private path so your resources can reach specific AWS services without requiring: Public IPs Internet Gateways NAT Gateways Direct internet routing Both endpoint types enable private connectivity, but they operate differently inside the VPC.

It is a common saying that "clients don't care about the stack you use for them" but I disagree. I think most devs don't know how to tell their clients to realise they care. You have a clear advantage if your clients are technical and you're able to communicate the benefits they will gain as a result of you skills in the stack and the general advantage of the stack in as much as you understand your clients. Being able to communicate your stack to your clients with the language they understand gives you advantages over someone who doesn't tell their clients the stack they use because they think clients don't care. For example, you can tell your client you're going to use React.js, GCP or AWS by saying: "We will build your app with the same technologies that power great companies like Google and Facebook so that you can sleep well at night." Saying this makes them realise you're trying to make sure they have stable apps like Google and Facebook. Wait! I strongly believe it is unethical to make this kind of claim when you're not skillful, willing and able to deliver. Above all, the point I am trying to make is that clients care about the stack you use for them if you know how to tell them. What do you think? If you agree, please give more insights on how to gain more advantages by telling you clients the stack you use but if you disagree, feel free to raise your case. Cheers!  ( 7 min )

Illuminating Bioprocesses: Dynamic Control with Light Imagine trying to steer a race car with only two settings: full throttle or brakes slammed. No finesse, no subtle adjustments. That's often how we've been controlling biological processes, leading to suboptimal results. But what if we could finally modulate cellular behavior with the precision of a dimmer switch? The core concept is dynamic light modulation for controlling genetically engineered cells. Instead of just blasting cells with continuous light, we precisely cycle the light source on and off, thereby adjusting cell responses with much greater resolution. Think of it like dithering in digital photography – creating shades of gray from black and white dots. This allows us to fine-tune protein production and metabolic pathways …  ( 7 min )

For the Kiroween Halloween hackathon, I set out to build something ambitious: an immersive, narrative-driven horror web experience where users "make a deal with the devil." The catch? I wanted it polished, production-ready, and atmospheric—not just a themed website, but a complete journey into the underworld. The vision: A four-screen experience with custom animations, horror music, video transitions, and a cohesive dark aesthetic. The timeline: Days, not weeks. 🤖 Enter Kiro AI The Development Flow Foundation (30 minutes) Me: "Set up Vite + React + TypeScript with Tailwind CSS. Kiro: Generates complete project structure, configs, and theme Component Building (Iterative) Me: "Create a landing page with graveyard background, Kiro: Builds LandingPage component with Framer Motion animations Me: "Now add a 5-step form where the devil interrogates the user."

In university, we learned Java and C++. When I started looking at web development, the number of choices was overwhelming. Django? Laravel? Spring Boot? Ruby on Rails? Eventually, I settled on the MERN Stack (MongoDB, Express, React, Node.js). Here is why I think it’s the best choice for new developers in 2024. 1. One Language to Rule Them All 2. JSON is Native 3. The React Ecosystem Conclusion Is MERN perfect? No. SQL is often better for complex data relationships. But for building a portfolio and getting hired fast? It’s hard to beat.  ( 6 min )

In today’s world, we are constantly connected to each other through various means of communication. One of the most popular methods of communication is through email, which allows us to send and receive messages at lightning-fast speeds. However, in the vast ocean of emails, there exists a lesser-known world that many people may not be aware of – the world of restricted email inboxes. In this tutorial, we’ll show you how to access restricted mailboxes and unblock restricted entities. Open the Microsoft 365 Defender portal. At the left menu, and below “Email & collaboration“, click on “Review“, and finally click on “Restricted entities“. Find and pick users you wish to unblock on the Restricted Entities page by clicking on them, then from the above ribbon click on “Unblock“. Follow the guide and unblock the user. In conclusion, restricted email inboxes may not be widely known, but they play an important role in maintaining secure and organized communication in various settings. They offer a level of protection for sensitive information and ensure that only authorized individuals have access to it. However, they also come with their own challenges, which users need to be aware of. As we continue to navigate the world of digital communication, it is important to understand and appreciate the various methods used to safeguard our information.  ( 6 min )

In AI regulation news today, governments worldwide are rapidly developing new rules to govern artificial intelligence. Global legislative activity surged in 2024–2025, with AI-related bills and proposals increasing by over 21% across 75 countries. At least 69 nations are pursuing more than 1,000 AI policy initiatives as of early 2025, reflecting diverse approaches. For example, the European Union’s risk-based AI Act sets strict standards for high-risk systems (e.g. requiring risk assessments and human oversight), while China’s 2023 AI rules mandate content labeling and limit prohibited outputs. In contrast, the U.S. currently relies on executive orders and sectoral guidelines rather than a single AI law.

NeoBASIC is a programming language I'm creating, still in the design phase, aiming to provide a better development experience while transpiling code into a compiled (and general-purpose) language. It's somewhat of an elastic language, combining the best of both worlds: Python (prototyping speed) and C++ (execution speed). The mention of BASIC is due to its faster learning curve, an effort I've been making to ensure the language can be used by computer science beginners. In the 70s and 80s, computer magazines contained BASIC programs for enthusiasts to type into their personal computers and calculators. These were short programs, often scripts or small routines. Some contained dozens of lines and required more time and care in typing. But this was never a problem for those who enjoyed progr…  ( 10 min )

AI didn’t replace how I code — it reshaped the habits around it. After months of using Copilot, ChatGPT, Cursor, and Windsurf daily, I realized the biggest gains weren’t from AI generating entire functions, but from the small workflow improvements I started forming along the way. These are the 10 AI habits that genuinely made me a faster and clearer developer — with real examples. 1. Starting Every Task by Asking AI to Break It Down Whenever I start a feature, I ask AI: “Break this into clear, actionable steps.” This one habit alone reduces confusion and prevents hallucinations. I even wrote about a similar trick in my article on a one-line hallucination fix for AI bots — and it still works. A clean plan turns even a vague feature request into something I can execute confidently. 2. Ask…  ( 8 min )

Why Law Firms in Industrial Property Protection Must Once Again Become the Vanguard of AI Sovereignty Guest article by Oliver Otto The legal profession has never been hostile to technology. In fact, it has long been one of the most economically rational and tech-forward fields. While other industries were still debating digitization, law firms had already integrated digital tools into daily operations. Word processing replaced typewriters for efficiency. Dictation became digital to save time. Speech recognition multiplied productivity. And in industrial property protection—especially in patent and trademark practices—automated deadline management, software-supported workflows, and database-driven IP administration were standard long before the term legal tech even existed.

RTF (Rich Text Format), as a cross-platform compatible rich text format, is widely used in document exchange and content storage scenarios. However, for practical requirements such as document preview, plugin-free display, and content archiving, converting RTF to image formats like PNG and JPG is a more optimal solution. This article focuses on C# development scenarios, starting from technical principles, and details the implementation logic, key steps, and optimization directions of RTF-to-image conversion to provide reference for development practice. The essence of RTF-to-image conversion is converting structured rich text data into pixel-level image data through a rendering engine. Its core process can be broken down into three key links, and the technical logic revolves around this ma…  ( 9 min )

Enhanced Security for Remote Access. In the world of Linux system administration and cybersecurity, how you access your server is just as important as what you do on it. Secure Shell (SSH) is the industry standard for remote administration, but relying solely on user passwords can leave systems vulnerable to brute-force attacks. A Linux machine (I am using Kali Linux in this demonstration). and start the SSH daemon(sshd) sudo service ssh start sudo service ssh status We will use ssh-keygen to create our cryptographic keys. In my implementation, I am using the ED25519 algorithm, which is currently considered more secure and faster than the older RSA standard. Press ENTER to accept the default location (/home/username/.ssh/id_ed25519). You will be asked for a passphrase(you can decide to enter kali). Crucial Security Step: While you can leave this empty, it is highly recommended to enter a strong passphrase. Inspecting the Keys Navigate to the hidden SSH directory to verify your keys were created: Navigate to the directory and ls to see the files created. For the server to recognize you, your public key must be added to the server's authorized_keys file. Since I am simulating this locally, I will copy the key to my localhost. ssh-copy-id -i ~/.ssh/id_ed25519.pub your-current-user@127.0.0.1 Success Output: Number of key(s) added: 1 To ensure the key was copied correctly, you can cat the authorized_keys file: using cat authorized_keys Now, log out or open a new terminal and attempt to SSH into the machine again: using ssh localhost At this point, enter the ""passphrase"" you entered above. By disabling password logins and relying on SSH keys, you significantly reduce the attack surface of your Linux servers. This exercise is a fundamental skill for any aspiring SysAdmin or Cybersecurity professional.  ( 7 min )

AI prompting has grown from a neat experiment into a skill that genuinely helps us work better. As AI becomes more capable, knowing how to communicate with it clearly isn’t just for engineers anymore — it’s useful for anyone who creates, analyzes, or builds things. This article is a practical, example-first guide to prompting, with simple visuals and real scenarios you can apply right away. A lot of the ideas here were inspired by Chip Huyen’s book AI Engineering, which approaches AI with a balance of clarity and practicality. Her perspective helped shape the way I think about prompting as a communication skill, not just a technical trick. Prompting is more than "asking AI a question." It is: How you frame a task How you guide the model's behavior How you structure information How you set …  ( 9 min )

AI prompting has evolved from a curiosity into a professional superpower.

First, there is so much to learn. Understanding ML foundational concepts and having AI-accelerated workflows doesn't mean you can just jump in without going through the hard curve of learning. I learned that the expensive way. Reinforcement Learning (RL) is distinct from other ML fields. Even though they share boundaries, there are concepts that even hardcore ML engineers won't just grasp immediately. My first mistake was trying to skip steps. I was ambitious, that was glaring. I wanted results ASAP (my self-destructive habit of posing to the world). I was way too focused on seeing it work without employing my intuition to the hard details. After completing my first RL project with AI's help, I could feel it in my gut: I had learned nothing, or maybe just too minimal to fit my acclaimed ac…  ( 8 min )

Prisma 7 just launched, and this isn’t your typical point release.

Most Vue developers work exclusively with the traditional browser DOM renderer—but Vue 3’s flexible architecture opens the door to much more. Thanks to the Vue Custom Renderer API, you can build interfaces that run far beyond the DOM, including WebGL scenes, Canvas UIs, terminal apps, game engines, or even native UI trees. This makes Vue not just a "web framework," but a universal reactive engine capable of driving any rendering target. In this article, we’ll explore: • What the Vue Custom Renderer API is and why it matters createRenderer() TresJS uses a custom renderer to bridge Vue and Three.js Enjoy!

Today marks the Day 7 of 30 Days Terraform challenge and today we will deep dive into the Terraform Type Constraints and how we have multiple type constraints in Terraform based on the value. Terraform divides the variables based on the values they hold. They are divided into 3 types such as Primitive, Complex, Any type. Primitive types are the simplest and most commonly used variable types in Terraform. Primitive types are powerful because they enforce strict validation and avoid unexpected results especially when performing comparisons or arithmetic operations.There are exactly three of them: Strings, Numbers and Bool. A string is simply text. Anything inside quotes i.e. "hello", "production", "ap-south-1" is considered a string. It’s one of the most frequently used types in Terraform b…  ( 10 min )

You're using Kotlin. You love coroutines. Your entire codebase is suspend functions, Flow, and structured concurrency. Then you need to consume messages from RabbitMQ. And suddenly, you're writing this: runBlocking { processMessage(message) } Congratulations. You just mass-deployed an anti-pattern. The official RabbitMQ Java client was designed in 2007. Kotlin coroutines were released in 2018. These two worlds don't mix well. Here's what consuming messages looks like with the Java client: val factory = ConnectionFactory().apply { host = "localhost" username = "guest" password = "guest" } val connection = factory.newConnection() val channel = connection.createChannel() channel.basicConsume("orders", false, object : DefaultConsumer(channel) { override fun handleDeliver…  ( 9 min )

Hashicorp Vault is a secrets management tool. It provides secure storage for access credentials, certificates, or general encryption/decryption processes. To get access to any secrets, tokens are issued, providing compact, fine-grained and time-based access controls. Tokens are fundamental to Hashicorp Vault. Operationally, it is a default authentication engine that can not be moved or recreated. Technically, tokens link static secret data or dynamic secrets data at an external application for a specific time. And conceptually, tokens can be short-lived in memory, renewable and persisted on disk, and even form parent-child relationship. This article explores and explains all aspects of tokens in Hashicorp Vault. It starts with an overview about the authentication method and data structure …  ( 11 min )

AWS networking includes multiple layers of traffic control, and two of the most important components are Security Groups (SGs) and Network ACLs (NACLs). They’re often compared because both filter traffic, but they operate at different layers and behave differently. Understanding how each one works helps you build clean and predictable VPC architectures. In this article, we’ll look at how they differ and how they work together inside a VPC. Security Groups act as virtual firewalls for individual resources, such as EC2 instances, load balancers, and RDS databases. They operate at the instance level, meaning the rules apply directly to the resource they’re attached to. A few key characteristics define how they behave: Stateful rules: If inbound traffic is allowed, the response is automaticall…  ( 8 min )

Introduction After writing new content, committing the markdown, and pushing to GitHub, my Astro build pipeline runs. Since my site is built with Astro, I have a custom integration I've written which runs at the end of the build process and cross-posts the markdown content of my articles to DEV and Hashnode. This workflow works, but the biggest friction point is images — specifically, how Astro handles them inside Markdown. Since I am cross-posting the raw markdown to other platforms, the markdown content includes image URLs relative to my project file system. When building the site, Astro automatically converts these relative URLs to canonical URLs with the site domain as the base. Here's an example of what these image URLs in the markdown look like:  Ho…  ( 9 min )

Intro: Sessions lingering indefinitely after the final message. These issues weren’t just technical annoyances — they impacted user experience, compliance, and bot reliability, especially in regulated industries. Native Inactivity Trigger: With Microsoft Copilot Studio, we now have a powerful tool to address this: the Inactivity trigger. Inactive Trigger This trigger allows bot authors to define what should happen when a user becomes inactive for a specified duration. You can: End the conversation gracefully with a closing message. Reset the session context to prepare for a fresh start. Escalate to a human agent or log the session for review. Customize the timeout duration based on your business needs. Use Case Example Wait for 15 minutes. Trigger a message like: “It looks like you’ve stepped away. I’ll close this session for now — feel free to start again anytime.” Reset the session so the next interaction starts fresh. Final Thoughts: The Inactivity trigger is a small but powerful addition that solves a long-standing issue in bot design. It brings clarity, control, and professionalism to your Copilot Studio experiences — especially in enterprise scenarios where session lifecycle matters.  ( 7 min )

You've just built a shiny new feature that lists user transactions. In testing, it runs flawlessly: fast responses, clean UI, no complaints. Then your biggest client joins with 50,000 records. Suddenly, that endpoint stalls and times out, and support tickets start piling up. This is a classic pagination problem. Instead of trying to load an entire data set at once, pagination breaks it into smaller, more manageable chunks (or pages) that can be fetched incrementally. Your bank does this; it shows around ten recent transactions at a time, not your entire account history. There's a good reason for this: research shows that even a one-second delay in page load can reduce conversions by 7 percent. When you're dealing with payroll systems, financial data, or anything time sensitive, those delay…  ( 14 min )

🧐 link to the practice repository: PRESS ME In the rapidly evolving landscape of AI, the ability to connect Large Language Models (LLMs) to your own data and tools is a game-changer. The Model Context Protocol (MCP) has emerged as a standard for this connection, allowing developers to build servers that expose data and functionality to MCP clients like Claude Desktop, VS Code, and others. In this article, we will explore what an MCP server is and build a simple "Weather Server" from scratch using Python. By the end, you'll have a working server that you can connect to Claude to ask for weather updates! An MCP Server is a lightweight application that implements the Model Context Protocol. It acts as a bridge between your data sources (databases, APIs, files) and an AI client. Instead of bu…  ( 8 min )

🧐 link to the practice repository: PRESS ME In the modern era of distributed systems and microservices, "monitoring" is no longer enough. We need Observability. But what exactly is the difference, and how can we implement it without getting lost in complex configurations? In this article, we will explore the core concepts of observability and build a real-world example using Python (Flask), Prometheus, and Grafana. While monitoring tells you when something is wrong (e.g., "The server is down"), observability allows you to understand why it is wrong by asking questions to your system from the outside. It is often categorized into three pillars: Logs: A record of discrete events (e.g., "User X logged in"). Metrics: Aggregated numerical data over time (e.g., "CPU usage is at 80%").

You crushed Q4. Sales were up. The holiday push worked. Your inbox is full of order confirmations and your analytics dashboard looks like a beautiful upward slope. Then January hits. Crickets. Here's the uncomfortable truth: most of those December buyers aren't coming back. Industry data shows that roughly 70% of first-time holiday shoppers never make a second purchase. They came for the deal, grabbed the gift, and moved on with their lives. Your carefully crafted brand experience? It ended at the shipping confirmation email. But here's what actually matters: the 30% who might stick around are worth 5-10x more than the one-time buyers. The math is simple. The execution? That's where it gets interesting. Most retention advice sounds like this: "Send a follow-up email! Create a loyalty progr…  ( 11 min )

If you've worked with NestJS for more than a day, you've seen this error: Error: Nest can't resolve dependencies of the UserService (?). Please make sure that the argument EmailService at index [1] is available in the UserModule context. You scratch your head. You added EmailService to the providers array. Why isn't it working? So you start randomly importing modules, adding services everywhere until the error goes away. Now your app works, but you have no idea why, and your modules are a tangled mess. This is one of the most common pain points for NestJS developers — both beginners and experienced ones. The module system is powerful but unforgiving.

When I built VBlog, a full-stack application with Next.js, Express, Prisma, and PostgreSQL, everything ran flawlessly on my local machine. Then I tried deploying it to another environment. 💥 Chaos ensued. Missing dependencies. Mismatched Node versions. Prisma binaries that refused to cooperate. PostgreSQL connection failures. The backend would work while the frontend crashed, or vice versa. That's when Docker shifted from a "someday" learning goal to an immediate necessity. In this article, I'll walk you through: Why Docker became essential for my project How I containerized each component of my stack The Prisma binary issue that almost broke me (and how I fixed it) My final docker-compose workflow that ties everything together My tech stack consisted of: Next.js 15 for the frontend Node.…  ( 8 min )

I originally posted this post on my blog. I definitely can't escape from legacy code. This time, it's an old WebForms application written in VB. Yes, that old. It's a family business. Dad started it. And years later, his two sons got involved. It's funny when during the standup meetings I hear, "Hey Dad..." The code is a mess. Sorry, I mean it needs a lot of care. I don't blame them. It was the easy route with WebForms. Just drag and drop, double-click, and dump all your logic. It's just like that framework encouraged people to copy and paste. I've worked with at least 3 legacy apps with WebForms. All of them were pure spaghetti code. Zero best practices. "Coincidence? I think not!" The code needs care, but the database needs even more attention. It doesn't have foreign keys, and queries d…  ( 7 min )

The golden age of "keyword stuffing" and generic 2,000-word guides is fading. Today, search engines have a singular focus: connecting users with direct, helpful answers. If your 2026 SEO strategy is still built solely around competing for broad, high-volume keywords, you are likely fighting a losing battle against industry giants. The real opportunity for growth lies not in chasing "head terms," but in answering specific questions. Here is why building a Question & Answer (Q&A) community is the most potent, scalable SEO strategy for the coming year, and how tools like AnswerGrowth can help you execute it. Google’s recent algorithm updates (specifically the "Helpful Content" system) have made one thing clear: content written for humans ranks better than content written for bots.

Google's New AI Tool Already Beaten? Try Alibaba's Free Local Alternative Last week I was figuring out how to access Google's Nano Banana Pro—dealing with VPNs, subscriptions, and daily usage limits. Then Alibaba dropped a bombshell: Z-Image-Turbo, a completely open-source AI image generator that runs locally on your machine with zero restrictions. I downloaded the one-click package and tested it immediately. This tool is absolutely brilliant. To be honest, previous attempts with Stable Diffusion to generate posters with Chinese text were disastrous—the characters would come out completely distorted. Z-Image-Turbo completely solves this pain point. I simply typed "a girl in traditional Chinese hanfu playing a guqin in a bamboo forest," and the output was stunning.

In the article How to evaluate the quality of a framework technology, I introduced a concept, framework agnosticism, and pointed out that the most ideal framework is one that you are completely unaware of when writing business code. Some readers asked: As of now, no business development is completely independent of frameworks—what is the point of this concept? A helpful classmate in the discussion group replied: Software development depends on frameworks because we need the framework-provided input/output, event callbacks, dependency injection, external data I/O, context, etc.—most of which are side effects that the program’s execution relies on. If, when implementing a piece of business, we design it as a library, explicitly declare all side effects as interfaces and context objects, and …  ( 17 min )

Few programming languages have shaped the software world as profoundly as C.

Chapter 6: Building Your Own Types Monday morning arrived with the scent of rain on concrete. Ethan descended the familiar stairs, coffee tray in one hand, a white bakery bag in the other. Eleanor looked up from her laptop. "What's the occasion?" "Croissants. The baker said they're architectural—all those layers held together by structure." She smiled. "Perfect. Today we're building structures of our own. Sit." Ethan set down the coffees and took his seat. "Structures?" "Structs. Go's way of creating custom types that group related data together. Until now, we've used Go's built-in types—int, string, bool, slices, maps. Today, we make our own."

If you have used Google’s Gemini and found it impressive but ultimately disconnected from your actual work, you aren't alone. Many users describe the initial experience as talking to a very smart stranger—it knows the capital of France and can write a haiku, but it knows absolutely nothing about you, your projects, or your schedule. However, the difference between Gemini being a novelty and a productivity powerhouse often comes down to a single, often overlooked toggle in the settings: The Google Workspace Extension. Out of the box, most AI chatbots operate in function independently. If you want Gemini to summarize a meeting note you wrote last week, you usually have to find the document, copy the text, paste it into the chat, and then ask your question. This friction defeats the purpose o…  ( 7 min )

An interesting question is: when a new framework technology emerges, how do we evaluate its quality? Since the NopORM engine was open-sourced this year, we’ve received some feedback, but most people likely didn’t grasp the theoretical part of NopORM, so the common confusion is: what concrete advantages does NopORM have over other ORM engines? In this article, I’d like to discuss objective criteria for evaluating a framework that do not hinge on personal experience, preferences, or familiarity. Interestingly, some people never read the theoretical parts themselves, but when discussing the gap between domestic and international software technology, their rhetoric is “domestic development emphasizes pragmatism, and the gap in software methodology is huge.” This can only be described as a “Lor…  ( 22 min )

Quantum Granules: Taming Complexity with Effect-Based Abstraction Quantum computing holds immense promise, but wrestling with its inherent complexity can feel like navigating a dense jungle. How do we abstract away low-level qubit operations and build more intuitive, manageable quantum programs? Imagine organizing quantum operations into reusable, effect-based units, much like organizing files into folders on your computer. The core idea is Quantum Granular Computing: treating groups of quantum operations as single, abstract units called "granules." Instead of directly manipulating individual qubits, we manipulate these granules, each representing a specific effect on the quantum state. These granules aren't just fixed blocks; they can morph and adapt based on context, providing a flexib…  ( 7 min )

Many people are confused when choosing LED light strips: What are the differences between RGB light strips and ordinary single-color light strips? In fact, apart from the different color effects, there are also essential differences in their control methods. Single-color light strips only emit a fixed color (such as warm white, pure white or red), have a simple structure, and usually only have two wires (positive pole and negative pole). As long as it is connected to the matching power supply, the light strip will remain on constantly. If dimming is needed, simply add a simple PWM dimmer or a smart switch. The operation is intuitive and suitable for basic lighting. Each LED of the RGB light strip contains three chips: red (R), green (G), and blue (B). By mixing the three colors, it can present 16 million colors. It usually has four wires: one common positive pole (+12V/24V), and the other three control the R, G, and B channels respectively. It must be used in conjunction with a dedicated RGB controller (such as an infrared, Bluetooth or Wi-Fi controller) and cannot be directly connected to a power source; otherwise, a short circuit may occur. For this reason, RGB light strips can achieve dynamic effects such as color change, gradient, and music synchronization, but the control is more complex. Monochrome light strips excel in simplicity and reliability, making them suitable for scenarios that do not require fancy effects. Therefore, for an atmosphere, choose RGB; for practicality, choose monochrome - provided that the correct controller and power supply are paired.  ( 6 min )

Introduction As a Senior Engineer, I’ve spent 5 years building scalable systems in Java and Angular. When I moved into AI, I noticed a pattern: many models live and die in Jupyter Notebooks. I wanted to build systems that survive in production. Here is how I architected two enterprise-grade ML solutions, focusing on Deployment, Explainability, and ROI. 1. The Architecture: Engineering First Before training a single model, I designed the infrastructure. A model is useless if it can't be queried at scale. Serving Layer: I chose FastAPI over Flask for its asynchronous capabilities and automatic validation (Pydantic), mirroring the type-safety I’m used to in Java. Containerization: Both projects are fully Dockerized, ensuring that the environment used for training matches production exactly. …  ( 7 min )

Introduction One thing that occurs in most programming languages is the desire to have type-generic code, that is code whose purpose or algorithms don’t depend on the type of data. Most commonly, this manifests as the desire to have generic “containers,” e.g., arrays, lists, or sets of some type T where T can not only be any type built into the language, but user-defined types as well, e.g., list of integers, sets of strings, etc. Different languages that support generic containers do so differently, e.g., C++ uses “templates” where type parameters are instantiated at compile-time with specific types, e.g., a list can be instantiated with T = int yielding list. C has only minimal support for generic code via _Generic and preprocessor macros. Some people try to use these things t…  ( 8 min )

Adaptive Gripping: Bridging the Dexterity Gap in Robotics Ever watched a robot struggle to pick up a thin sheet of glass or open a cabinet without a handle? Current robotic grippers often falter on tasks requiring both delicate touch and secure hold, limiting their real-world usability. The solution? Imagine a robotic hand that combines the precision of fingertips with the power of suction. We're talking about a hybrid end-effector, seamlessly integrating a traditional gripper with a miniature vacuum system. This allows robots to switch instantly between gripping and suction, or even use them in tandem for ultimate control. It's like giving a robot the ability to both pinch and stick, adapting to a much wider range of objects and surfaces. This combined approach unlocks a new level of ad…  ( 7 min )

Hey everyone! 👋 3-month journey of DataViz Kit, I’m back with another post. If you remember, I mentioned having a few "techniques up my sleeves" to try and crack the SEO code, especially since Google has been a tough nut to crack compared to Bing. Here is what I’ve been working on this week and how the numbers are looking. 🧪 The Experiments Programmatic SEO / Content Clusters: I started crafting articles for specific use cases. 📈 The Numbers (Week 1 Update) Bing: The growth is steady. The Heatmap Maker is still the star player here, bringing in about 50-100 clicks this week. Google: Still the "silent observer." I'm seeing impressions creep up slightly for new keywords, but clicks are flat. I suspect the changes I made this week will take 2-4 weeks to reflect here. 🛠️ Feature Updates Update: I pushed a small fix to the headers. Coming Soon: I’m experimenting with a new chart type. If the testing goes well, it should be live soon. 💭 Thoughts for the Week If you haven't checked it out yet, try my tool by creating a box plot, and let me know what's your opinion. See you in the next update. ✌️  ( 7 min )

The API receiving the request has no idea if it was a valid user intent or a rogue agent. The request is just anonymous JSON. We need Attribution. We need the agent to SIGN its work. Prefer a visual explanation? I broke this architecture down into a 6-slide carousel on LinkedIn. It covers the "Why" and "How" in under a minute. I built the Agent Identity Protocol (AIP) to solve this. It is an open-source tool that gives your agent a local crypto wallet. Instead of just executing a tool blindly, we force the…  ( 8 min )

You're Not Building Netflix: Stop Coding Like You Are Adam - The Developer ・ Nov 23 #webdev #programming #architecture #typescript  ( 6 min )

View demo https://codepen.io/kspmultimedia/live/MYaGPmP Hi! I don't usually post much here but here's something I've been thinking about lately: I recently rebuilt this set of progress buttons as a practice project exploring how motion can communicate state change. Each button uses the same dark green fill but expresses progression differently: one flows horizontally, another condenses as it fills, and the third uses 3D perspective for a more dimensional feel. Motion Isn't Decoration — It's a Design Decision *Guide attention Meaningful Motion Helps People — Not Distracts Them Here are some principles I use: Story first, motion second Instead of adding animation to fill space, I ask: "What is the emotional or informational moment here?" Motion should amplify intent, not distract from it. Micro-interactions > big animations Subtle hover states, soft easing, scroll cues, gentle reveals — tiny moments make interfaces feel alive without overwhelming users or slowing sites down. Purpose before aesthetics Motion can highlight hierarchy, signal change, or guide direction. If it doesn't support the user journey, it's just noise. Accessibility is part of animation Reduced motion settings, predictable timing, readable transitions — this is how animation becomes inclusive instead of exclusive. Where I'm Growing Next If you're: *Exploring motion in Webflow or GSAP, I'd love to trade notes. *If you have examples of meaningful motion, share them — I'm always learning. *Just want to connecting, please do :)  ( 7 min )

Chinese artificial intelligence startup DeepSeek released two powerful new AI models on Sunday that the company claims match or exceed the capabilities of OpenAI's GPT-5 and Google's Gemini-3.0-Pro — a development that could reshape the competitive landscape between American tech giants and their Chinese challengers. The Hangzhou-based company launched DeepSeek-V3.2, designed as an everyday reasoning assistant, alongside DeepSeek-V3.2-Speciale, a high-powered variant that achieved gold-medal performance in four elite international competitions: the 2025 International Mathematical Olympiad, the International Olympiad in Informatics, the ICPC World Finals, and the China Mathematical Olympiad. The release carries profound implications for American technology leadership. DeepSeek has once aga…

When Liquid AI, a startup founded by MIT computer scientists back in 2023, introduced its Liquid Foundation Models series 2 (LFM2) in July 2025, the pitch was straightforward: deliver the fastest on-device foundation models on the market using the new "liquid" architecture, with training and inference efficiency that made small models a serious alternative to cloud-only large language models (LLMs) such as OpenAI's GPT series and Google's Gemini. The initial release shipped dense checkpoints at 350M, 700M, and 1.2B parameters, a hybrid architecture heavily weighted toward gated short convolutions, and benchmark numbers that placed LFM2 ahead of similarly sized competitors like Qwen3, Llama 3.2, and Gemma 3 on both quality and CPU throughput. The message to enterprises was clear: real-time…

A stealth artificial intelligence startup founded by an MIT researcher emerged this morning with an ambitious claim: its new AI model can control computers better than systems built by OpenAI and Anthropic — at a fraction of the cost. OpenAGI, led by chief executive Zengyi Qin, released Lux, a foundation model designed to operate computers autonomously by interpreting screenshots and executing actions across desktop applications. The San Francisco-based company says Lux achieves an 83.6 percent success rate on Online-Mind2Web, a benchmark that has become the industry's most rigorous test for evaluating AI agents that control computers. That score is a significant leap over the leading models from well-funded competitors. OpenAI's Operator, released in January, scores 61.3 percent on the sa…

As AI, cloud, and other technology investments soar, organizations have to make investment decisions with increased speed and clarity. Practices like FinOps, IT financial management (ITFM), and strategic portfolio management (SPM) help stakeholders evaluate opportunities and trade-offs for maximum value. But they depend on unified, reliable data. And that’s often where the challenge begins. AI can surface insights from data within specific domains, but important decisions rarely rely on a single source of data. To account for operational and organizational factors as well as financial impact, finance and IT teams have to cut through disconnected systems, outdated data, and inconsistent definitions of value. Real control over technology spend comes from financial intelligence — turning frag…

With some needed infrastructure now being developed for agentic commerce, enterprises will want to figure out how to participate in this new form of buying and selling. But it remains a fragmented Wild West with competing payment protocols, and it's unclear what enterprises need to do to prepare.  More cloud providers and AI model companies will start providing enterprises with the tools needed to begin building systems that enable agentic commerce. AWS, which will list Visa’s Intelligence Commerce platform on the AWS Marketplace, believes that making it easier to connect to tools that enable agentic payments would accelerate the adoption of agentic commerce.  While this doesn’t mean Amazon has formally adopted Visa’s Trusted Agent Protocol (TAP), which would bring the world’s largest e-co…

The Paradox of Documentation Drift 🤖 A few months ago, I hit a wall. Using LLMs, I was shipping code faster than ever. Features were flying out the door. But three weeks later, when I had to debug a module I wrote... I had the code, but I had lost the context. I realized I was suffering from the silent killer of velocity: Documentation Drift. The code evolves, but the map stays static. I tried the "good developer" rituals—comments, Confluence updates, and manually drawing diagrams in Miro. But the moment I merged a new PR, the diagrams were dead. The Validation (We Need Maps, Not Books) 🧠 The answers confirmed my thesis: The problem isn't laziness. It's architecture. "Separate docs get stale and are often worse than useless." The truth is: We need living maps, not static books. The Solution: Building MIVNA 🛠️ The Result: Zero Drift, Zero Shadowing 📉 Visual First: Automatically generates high-level architecture diagrams. Legacy Safe: Instantly map that scary legacy module without needing a Senior Dev to "shadow" you for 3 days. Always Sync: If the code changes, the diagram changes. Period. I Need Your Help (Private Beta) 🧪 I’m opening the Private Beta for engineering teams who are tired of "Wiki Rot." I’m not looking for customers; I’m looking for builders to break it and tell me what sucks. Question: Does MIVNA fit your workflow? Do you prefer the diagrams in the PR or a centralized dashboard? 🔗 Check it out here: https://mivna-diagrams.lovable.app/ Let me know your thoughts in the comments!  ( 7 min )

Over the weekend I started the Introduction to Statistics in Python course, what stood out for me is numerical summary statistics - Measure of center. They help us summarize our data but choosing the correct "average" that truly represents the data is very important, else we will be fooled by extreme values. Data can lie to you if you use the wrong average. Imagine 5 kids with these allowances: ₦100, ₦120, ₦110, ₦130, ₦1,000,000 We use mean when the data is symmetrical (evenly spread) because: We use median when the data is skewed (has very big or very small values) because: In Real life: Recruiters use median salary, not mean, so one billionaire doesn't distort pay expectations. Learning this over again, made me understand the topic more clearly. Even on days when learning feels heavy, I'm grateful for every concept I now understand better than yesterday. -SP 🤍  ( 7 min )

AES is a symmetric-key encryption algorithm that is considered extremely secure, very easy to implement, and used in real world.

Running a business today means wearing many hats. You manage operations, talk to customers, close deals, plan growth, and solve unexpected problems. But while you handle all of that, one thing remains constant: customers will always have questions. And when those questions come in after working hours, during meetings, or when you're away from your devices, you risk losing potential sales, opportunities, and trust. This is exactly why every business, small or large, now needs an AI customer bot. Every time a customer reaches out and doesn't get a response, several things happen. They leave your site, choose a competitor, assume you're unavailable, or simply lose interest. Human support teams can't always be online. Traditional chatbots don't understand real business context.

Lately, I've seen more developers online starting to side eye MCP. There was a tweet by Darren Shepherd that summed it up well: "Most devs were introduced to MCP through coding agents (Cursor, VSCode) and most devs struggle to get value out of MCP in this use case... so they are rejecting MCP because they have a CLI and scripts available to them which are way better for them." Fair. Most developers were introduced to MCPs through some chat-with-your-code experience, and sometimes it doesn't feel better than just opening your terminal and using the tools you know.

The Project This week I was trying to work on a simple Deep Learning project to get familiar with PyTorch APIs. Since I had just returned from a staycation where I drove a rental car for over 600 miles, I decided to build a "Car Damage Classifier." I kept the goal simple: the model classifies if an uploaded image of a car is "DAMAGED" or "UNDAMAGED". I couldn't find a ready-to-use dataset, so I created one by merging a damaged car dataset (source: [lplenka/coco-car-damage-detection-dataset]) and a new car dataset (source: [yamaerenay/100-images-of-top-50-car-brands]). I made sure I roughly had the same number of images in my training set to avoid class imbalance. I began training using ResNet-18 as the backbone. Just after 10 epochs, my code reported a validation accuracy of 95.08%. I w…  ( 7 min )

GitHub Home That was in an IoT data processing platform project where we needed to handle hundreds of thousands of device connections simultaneously. Devices generate high-frequency data reporting while requiring real-time control command reception. This bidirectional communication scenario has extremely high requirements for connection management, where any minor performance loss gets amplified into significant problems. In the early stages of the project, we used a popular Node.js framework. In actual deployment, when connection numbers exceeded 50,000, server CPU usage soared to 95%, and response latency increased from a few milliseconds to several hundred milliseconds. Even worse, memory usage grew linearly, quickly reaching the system's physical memory limit. The technical team tried …  ( 9 min )

Why Buddhist Cognitive Science Explains What Neuroscience Cannot I spent five years studying the anatomy of the mind while teaching alongside monks in Himalayan monasteries.

And if you feel stuck, anxious, looping, or overwhelmed, Your brain isn’t broken — your map is. The Mind Is the Map Running on It.** Most mainstream content acts like mental suffering comes from a faulty chip: “Your amygdala is hijacking you.” “Your prefrontal cortex is under-regulated.” “Your dopamine baseline is off.” “Your cortisol is high.” This is reductionism disguised as explanation.

With thanks to The Oatmeal for the cover art. See also: enshittification. Please consider reading this post on autonomousapps.com instead. This will be my last post on the site dev.to. I’ve been posting my blog to that site since April 2018. My very first post was written when I was the Android team lead at Chess.com, titled Rewriting Chess.com’s Android app. Over the years, I’ve been more or less active, and have published 42 posts in all (counting this one).1 I’ve had concerns about the long-term viability of my presence on that site for a few years, as I’ve observed layers and layers of cruft accumulate around my actual content. I always had higher priorities though, and justified the cruft by recognizing that the site is providing a free service, and it frankly makes posting a tech blog to the internet fairly easy. The last straw came when, after my most recent post, two separate people contacted me about their experience trying to read it (one of them twice). First I was told that there’s a kind of soft login wall when visiting the post. I wasn’t aware of this because, as a writer on the site, I’m always logged in. The wall opens when interacting with one of those annoying popups so common on the Web these days: Note there’s only one option. Clicking it leads to this: Which fortunately can be dismissed. This is a dark pattern. Then later, someone sent me a screenshot of what it looks like after the login cruft has been brushed away: I’ve helpfully highlighted the portions of this screencap that are actual content. 21% of the screen real estate! And more than half the remaining is an ad for some bullshit “AI” product. Let me state this very clearly: fuck “AI.” It’s pure marking speak for a set of technologies founded upon harm, whose primary use-cases are harm. I want nothing to do with it. An auspicious number. ↩  ( 7 min )

Social platforms produce large volumes of unstructured conversations. Natural language processing enhances social listening by isolating sentiment, identifying topic keywords, and recognizing named entities such as product names or brands. This helps businesses monitor reputation, track market perception, and discover trending issues. Entity-aware sentiment provides deeper insight because it reveals not only whether users feel positive or negative, but exactly what they are responding to. Social listening tools use these techniques to categorize conversations at scale and detect emerging opportunities or risks.

Introduction In the world of networking, the OSI Model serves as a universal blueprint for how data travels across networks. Developed by the International Organization for Standardization (ISO) in 1984, it breaks down complex data transmission into seven distinct layers. For developers, network engineers, and DevOps pros, understanding the OSI Model demystifies everything from HTTP requests to TCP sockets in Node.js. It's not just theory—it's the foundation of modern network protocols, helping you troubleshoot and build robust applications. The OSI (Open Systems Interconnection) Model is a conceptual framework that standardizes communication between devices. It divides networking into seven layers, each handling specific tasks like error detection or routing. Unlike the simpler TCP/IP m…  ( 8 min )

Why I built this For many Firebase projects, a lightweight headless CMS is incredibly useful — whether it’s to integrate a small blog, manage app content, or simply provide a structured way to handle Firestore data. There are not many choices which are well integrated with Firebase. In fact its's FireCMS or Flamelink. I like the integration of FireCMS, but for simple projects the full framework can feel a bit heavy. So I built my own alternative using Svelte 4. FireCMS is great in many ways, but for my use cases it often felt like more than I needed. The data model system is impressive, but sometimes the flexibility becomes complexity. The UI also didn’t quite fit how I wanted to work: large tables are hard to navigate, editing inside popups feels clumsy, and handling subcollections neve…  ( 8 min )

Introduction Imagine sending a letter without an address—your data packets in networking face the same chaos. Enter port numbers: the unsung heroes that direct traffic to the right application on a device. In modern networking, port numbers are crucial for everything from web browsing to running a Node.js server. Whether you're a developer debugging connections or a DevOps engineer optimizing infrastructure, understanding ports demystifies TCP/UDP protocols and boosts your troubleshooting skills. Let's dive in. Port numbers are 16-bit unsigned integers (0–65535) that act like apartment numbers in a massive building—your IP address is the building, and the port specifies the exact door. They identify specific processes or services on a networked device, ensuring data reaches the intended …  ( 8 min )

Introduction In today's hyper-connected world, where cyberattacks strike every 39 seconds, network security isn't optional—it's survival. Enter the firewall: your digital bouncer, enforcing rules to shield trusted networks from malicious traffic. As a cornerstone of cybersecurity, firewalls prevent unauthorized access, block malware, and mitigate DDoS attacks. Whether you're a developer hardening a Node.js app or a DevOps engineer fortifying infrastructure, understanding firewalls is key to building resilient systems. Let's break it down. A firewall is a security device or software that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

It was supposed to be a smooth EKS migration. Instead, a handful of users started complaining about painfully slow logins — 20 to 40 seconds long. Oddly, others saw no issue at all. What followed was a three-hour debugging marathon that took us through Cloudflare cache rabbit holes, pod benchmarking, and finally, an AWS ALB subnet misconfiguration. What makes this story worth telling is not just the root cause (a bad ALB IP), but the full forensic process — every command, every false lead, and the eventual breakthrough. This is an engineering playbook, shared so you don’t waste the same hours the next time you face an intermittent latency mystery.

If you press your finger against water, it pushes back. That invisible resistance, surface tension, keeps the liquid whole even when disturbed. Good software has something like it. Some systems hold together when you change them; others leak at the slightest touch. The difference lies in integrity — the way a system manages its side effects without losing its shape. I've seen codebases that felt strangely calm, where every possible state meant something real and nothing arbitrary could slip in. Others allowed nonsense to exist, and from there, entropy spread quietly like cracks beneath paint. Type systems, invariants, and boundaries exist to make meaning explicit. They define where things start and stop — what’s allowed, and what isn’t. Without that structure, logic turns soft; assumptions…  ( 8 min )

There's a lot of hype around coding agents and the discourse can be annoying. I've always been into new shiny tools though. I'm forever messing with editors, IDEs, CLIs and anything else that seemed useful. Many of which no longer exist. In college we learned to code in assembly. C seemed very simple by comparison. Then object oriented languages and scripting seemed quaint. IDEs with refactoring and autocomplete made coding much easier. Tools like React and the ability to install npm packages made hacking a UI together somewhat less miserable and then before long somehow much more miserable. I had to take time to learn each new thing before it became useful but I enjoyed the learning. Now it's LLMs and agents. They're different but it's a similar feeling.

Sentiment polarity is one of the most commonly referenced outputs of a sentiment analysis model, yet it is often misunderstood. Polarity measures the direction and intensity of emotional tone within a piece of text. A high positive polarity indicates strong approval, satisfaction, or optimism, while a negative polarity reflects criticism, frustration, or concern. Values close to zero tend to represent neutral or balanced language. Polarity is valuable because it allows analysts and applications to quantify subjective language in a measurable way. This makes it easier to sort user feedback, analyze trends, and classify responses automatically. Even though polarity is a simple metric, it forms the foundation for more advanced sentiment and emotion modeling.  ( 6 min )

Real-time codebase indexing with CocoIndex lets you turn a messy, evolving repo into a live semantic API that your AI tools, editors, and SRE workflows can query in milliseconds. Most AI coding agents and RAG stacks fall apart on real-world code because they rely on brittle regex search, static embeddings, or manual sync scripts that constantly drift out of date. A proper index solves three hard problems at once: semantic chunking (what to embed), incremental updates (what to reprocess), and fast similarity search (how to query). CocoIndex packages these into a declarative flow: define sources, transforms, and storage once, then keep your index fresh with a single CLI command. Once your repo is indexed, you get a universal "code context service" that many tools can plug into. Some examples…  ( 10 min )

Hello, I'm Ganesh. I'm working on FreeDevTools online, currently building a single platform for all development tools, cheat codes, and TL; DRs — a free, open-source hub where developers can quickly find and use tools without the hassle of searching the internet. If you run a server with limited resources—specifically, standard 4GB RAM and 2 vCPU setup- you are likely familiar with the constant, stressful balancing act between performance and security. You know you need antivirus protection and system audits. You know the risks of leaving a server vulnerable to intruders, malware, and data theft. But you also know that running a standard security scan on a lean VPS can be a death sentence for your uptime. Ultimately, you are forced into a terrible choice: leave the server vulnerable, or ri…  ( 8 min )

If your system could testify, AIDE would be its expert witness. proving it. trust but verify itself. Introduction I’ll be the first to admit: encryption isn’t my strongest area. Sure, I’ve worked with public and private keys for SSH authentication and have signed keys before, so I’m not entirely new to the topic. But I hadn’t really explored how cryptography ties into system integrity — until now. In the first article of this series, we installed and configured AIDE (Advanced Intrusion Detection Environment) — a silent guardian that fingerprints your Linux system and detects when files change unexpectedly. It’s an excellent tool for monitoring file integrity, but it raises an important question: If AIDE verifies the integrity of your files, who verifies the integrity of AIDE?…  ( 9 min )

Ever stared at a folder with thousands of PDF invoices, resumes, or reports and thought, "There has to be a better way"? Spoiler: there is. At WeSpark Automations, we recently built a PDF data extraction pipeline that processed over 30,000 documents—scanned images, digital PDFs, multi-page forms—and pushed clean, structured data straight into Google Sheets. Zero manual copy-paste. Zero coffee-fueled all-nighters.​ Here's how we did it using n8n, OCR, and a bit of AI magic. The Problem: Manual PDF Hell Invoices with vendor names, amounts, dates buried in tables​ Resumes with inconsistent formatting across Word, PDF, and scanned images​ Financial reports locked in multi-page, image-heavy files Extracting data manually is slow, error-prone, and soul-crushing.

A dev resume isn't just a list - it's a context + impact sales doc. After reviewing more than 25 developer resumes (mobile, backend, fullstack, career changers, etc.), the same 3 mistakes kept showing up. The most common error: the whole resume is written like this: "Development and maintenance of applications..." "Worked on bug fixes and new features..." "Responsible for system X..." That says nothing about: the size of the problem, how hard what you did was, the impact on the product or business. Recruiters read this all day. It turns into noise. Fix: turn each bullet into technical action + what + how + metric/scale Another classic: a beautiful resume full of columns, icons, colors, emojis, and creative UX... and completely indigestible for someone who needs to read fast (or for an ATS). Lots of people fell into these: Multi-column layout, heavy sidebar, icon, emoji in dates, cluttered header Inconsistent dates and sections ("Aug 24", "08/2024", "2024 - present") Important sections missing or weak: Projects, poorly separated Skills, giant text blocks Fix: One column only FAANG LaTeX template Saw this a lot: giant skills list (Java 8 years, Docker, Kubernetes, AWS, Flutter, React...) without showing it once in roles technologies only in the "Skills" section, zero proof in experience or projects missing basic dev keywords: Git, testing, CI/CD, REST API, cloud, even for people who clearly use them daily career in infra/support or teaching, but resume saying "full-stack dev" without a real project/product described Fix: Only list tech you can defend in an interview and tie each one to a role or project.  ( 6 min )

Trying to understand JavaScript closures? ⭐ 1. The Backpack Analogy You pack a backpack at home. That’s basically a closure — a function carrying variables even after the parent function is done. ⭐ 2. The Waiter Analogy You tell a waiter your order: table number, dish, special instructions. That memory he carries along → that’s a closure. ⭐ 3. The Note From a Parent A parent gives their child a secret note. The note = the variables preserved by a closure. ⭐ 4. The Security Guard Analogy A boss gives a guard a list of allowed people and then goes on vacation. The guard remembering the list = closure. ⭐ 5. The Recipe Book A chef hands you a recipe book and closes his restaurant. That recipe book is exactly what a closure feels like. ⭐ 6. The Spare Key Someone gives you a key before moving abroad. The key you keep is the closure’s stored variable. ⭐ 7. The Childhood Tattoo Something meaningful happens when you’re young — and it stays with you forever. That tattoo = a closure holding on to past variables. 🎯 Quick takeaway A closure is simply a tiny bundle of memory that a function takes along with it, even after the place where that memory was created no longer exists.  ( 7 min )

📘 Introduction When we work with containers, we usually need to configure a lot of To make this process much simpler, AWS released ECS Express Mode, a It's a fast way to deploy a containerized application using Amazon ECS. In just a few clicks or commands, you'll have a running service with ECS Express Mode configures infrastructure for you that normally takes ✔️ An Application Load Balancer (ALB) ✔️ CloudWatch Logs ✔️ IAM Roles ✔️ VPC, subnets, and security ✔️ Autoscaling Very little. Just: The container image Service port (if not using the standard one) Any environment variables or secrets (if needed) Optionally, CPU and memory Everything else can remain automatic. Yes. If you already have experience, you can modify: Existing VPC and subnets Security group Log group name Container startup command Health checks Resource limits Scaling configuration But if you're just starting out, it's best to leave everything in Because it lets you focus on what matters: your application. Learning cloud often means dealing with networks, permissions, security, Learning containers Practicing deployments on AWS Creating a project for university Building an MVP or prototype Preparing for cloud certifications You can focus on the workflow without getting lost in advanced details. Although very practical, keep in mind: The ALB has a cost; if you create several services, each one may generate its own load balancer. If you need a complex architecture, Express Mode might fall short. It's perfect for getting started, but large projects may require more advanced ECS configuration.

AI may be changing the world of programming, but some human holiday traditions continue. Hundreds of thousands of coders await this year's "Advent of Code" event with its daily holiday-themed programming puzzles. And this year event creator Eric Wastl has made some more changes to discourage using AI. The site's FAQ list now specifically tells users that they shouldn't use AI when solving puzzles. “If you send a friend to the gym on your behalf, would you expect to get stronger?" And he's also removed the global leaderboard - a change long overdue, according to one a response he received from a commenter on social media.

hello everyone I’ve been tired of paying $60/year just to securely share Netflix and WiFi passwords with my family. I wanted to build a lightweight, secure alternative that runs entirely on the Edge and is only 5$ per year! Here is how I built EazyPasswords, a Zero-Knowledge vault that costs me almost nothing to run, thanks to the modern serverless stack. The Stack I wanted instant load times and zero cold starts, so I avoided traditional containers. Database: Cloudflare D1 (SQLite at the Edge). Frontend: Vanilla JS (hosted on Cloudflare Pages). Crypto: Native Web Crypto API (window.crypto.subtle). The Architecture: True Zero-Knowledge The biggest challenge was ensuring I (the server admin) could never see the user's data. . Why Cloudflare D1? I need your feedback (Beta) And if you have any questions about something you dont get feel free to ask Eazypasswords (If you sign up during the beta, you get the Family Plan for free forever as a thank you for testing).  ( 7 min )

Disabling local user accounts on all domain‑joined client computers via Group Policy is a valuable security practice. It ensures users only log in with domain accounts, preventing the risks associated with unmanaged local accounts, such as weak or shared passwords. Local accounts can be security risks if passwords are weak or shared among users. Domain accounts allow centralized control and auditing, improving security. Disabling local accounts centrally via Group Policy (GPO) avoids manual configuration on each machine, ensuring uniform policy enforcement. You must have an Active Directory domain with Windows Server 2016, 2019, or 2022 and domain-joined Windows 10/11 clients.

I came across a post from ArkType recently: Regex patterns being parsed at compile time! TypeScript inferring exact string literals like "ac" | "abc" from the pattern "^ab?c$". Not just string, but the actual possible matches. That got me curious. Regex has always been a runtime thing, you write a pattern, match strings against it, and the type system just sees string everywhere. But this was doing it all at compile time. I wanted to understand how, so I decided to build a minimal version myself. ArkType Regex is a compile-time regex parser written entirely in TypeScript's type system. Instead of just validating that a string might match a regex at runtime, it infers the exact string literal types that a regex can produce. For example: // Traditional regex: gives you `string` const match …  ( 14 min )

A lot of people say that “real backend performance” only comes from using Go, Rust, or Python. JavaScript and TypeScript often get labeled as frontend only languages. Here are five reasons why you don’t really need to abandon JavaScript or TypeScript for backend work. Bun is unbelievably quick. It starts fast, handles requests efficiently, and comes with tooling that feels smooth to use. Your frontend uses JS, your backend uses TS, your tests and tooling use the same language too. npm is basically a giant supermarket of libraries. Whatever you need, it’s probably there already. ElysiaJS and Hono are simple, fast, and don’t bring a bunch of unnecessary features you’ll never use. TypeScript gives you great type safety and confidence while coding. There’s a great explanation in this video that breaks everything down really well. https://www.youtube.com/watch?v=DpDHPoStZZ8  ( 7 min )

I just migrated away from long-term AWS access keys. Took me just 5 minutes. The Old Way Then AWS quietly released something that changes everything: aws login My Migration Story Step 1: Update AWS CLI aws --version Step 2: Delete Those Permanent Keys ~/.aws/credentials, saw the familiar aws_access_key_id and aws_secret_access_key staring back at me, and just... deleted them: rm ~/.aws/credentials I kept my region and output format in the config you still need those. Step 3: The Magic Moment aws login My browser opened automatically. I signed in with my regular AWS console credentials the same email and password I use every day. No copying and pasting 40-character strings. No "wait, which key was for which account?" Within seconds, I was authenticated: You are now logged in as arn:aws:iam:::user/your-user Credentials stored for profile 'default' Step 4: Verify It Worked aws sts get-caller-identity It worked. No access keys in sight. Just clean, secure, temporary tokens doing their job. What Makes This Better? They expire in hours, not years, They auto-rotate every 15 minutes You can check the expiration yourself cat ~/.aws/cli/cache/*.json You'll see something like: { "Credentials": { "AccessKeyId": "...", "SecretAccessKey": "...", "SessionToken": "...", "Expiration": "2025-01-01T12:34:56Z" } } The Bottom Line The entire migration took me 5 minutes. five minutes to eliminate one of the biggest security headaches in cloud development. If you're still using long-term access keys in 2025, this is your sign: Update your CLI to v2.22+ Delete those credentials Run aws login Your security team will thank you. Your future self will thank you. And honestly? It just feels better knowing those permanent keys aren't sitting there anymore.  ( 7 min )

If you were building web applications during the first dot-com boom, chances are you wrote Perl. And if you’re now a CTO, tech lead, or senior architect, you may instinctively steer teams away from it—even if you can’t quite explain why. This reflexive aversion isn’t just a preference. It’s what I call Dotcom Survivor Syndrome : a long-standing bias formed by the messy, experimental, high-pressure environment of the early web, where Perl was both a lifeline and a liability. Perl wasn’t the problem. The conditions under which we used it were. And unfortunately, those conditions, combined with a separate, prolonged misstep over versioning, continue to distort Perl’s reputation to this day.

The Architecture of Inevitability We've been sold a myth about self-discipline. It’s a story of grit, of white-knuckled willpower, of forcing yourself to do the hard thing through sheer mental brute force. This is a losing strategy. It treats the human mind like a flawed machine to be whipped into submission. It’s exhausting, and it rarely works long-term. True mastery of self and time isn't about becoming a better taskmaster. It’s about becoming a better architect. It's about designing a system—an environment, a set of rules, a protocol for energy—where the desired outcome is not just possible, but inevitable. You don't need more discipline; you need a better system. The Operating System: Three Core Principles Every effective system runs on a clear set of principles. For personal mastery,…  ( 9 min )

If you’ve played with AI chatbots or agentic frameworks lately, you’ve probably had the same moment I had - most agents can plan, reason, call tools, run workflows… yet somehow they can’t remember something you said 10 minutes ago. It’s impressive and frustrating at the same time. That gap — between advanced reasoning and almost no memory — is quickly becoming one of the biggest things holding AI agents back from feeling genuinely helpful. The Real Bottleneck Isn’t the Model. It’s the Memory. Most AI chat systems implemented today still live inside the model’s context window. Whatever fits in the prompt is what the agent “knows,” and the moment you step outside that window, it’s gone. That creates familiar issues: You keep repeating yourself The agent forgets your preferences Every new r…  ( 8 min )

Type constraints in Terraform play a crucial role in writing predictable, reusable, and maintainable infrastructure-as-code. When working with AWS resources, ensuring that your variables are properly typed helps prevent configuration errors, enforces standards, and makes your modules easier to understand and more robust. This post explains Terraform’s type system in depth and demonstrates how these type constraints apply to AWS infrastructure deployments. Terraform uses type constraints to ensure that variables receive values in the correct format. Without proper typing, it becomes easy to pass the wrong kind of data into your AWS resources, leading to failed deployments or hidden configuration issues. Types also help teams maintain consistency, validate expectations, and build self-docume…  ( 8 min )

Untouchable: The Future of Robotics is Magnetic Tired of robots limited by clumsy grippers and delicate surfaces getting scratched? Imagine a world where machines can manipulate objects with precision, without ever making contact. We're on the cusp of a revolution in robotics, moving beyond physical interaction to master the art of non-contact manipulation. The key is leveraging magnetic fields to levitate and control objects in 3D space. By precisely orchestrating a network of electromagnets, we can create a "magnetic hand" capable of moving, rotating, and positioning items with incredible accuracy. Complex control algorithms, trained using deep reinforcement learning, manage the electromagnetic forces to achieve stable and predictable movements. Think of it like playing a 3D chess game…  ( 7 min )

Epic CEO Tim Sweeney Urges Steam: Remove 'Made with AI' Game Tags\n\nSteam, a dominant PC gaming platform, recently introduced \"Made with AI\" tags for games to provide transparency to players regarding the use of generative AI in game development. This move was intended to help consumers make informed choices and navigate the evolving landscape of AI-powered content creation, especially given ongoing discussions about intellectual property and ethics in AI. Publishers are required to disclose if their games use AI to generate assets, code, or other elements, categorizing AI use into pre-generated or live-generated content.\n\nHowever, Epic Games CEO Tim Sweeney has publicly urged Steam to reconsider and remove these \"Made with AI\" tags. Sweeney argues that AI, fundamentally, is just an…  ( 17 min )

The following is the conversation with… just kidding 😄 This year, I attended the Lviv IT Arena. I met a few founders there and asked each of them to describe the very beginning of their entrepreneurial journey. If you’ve ever daydreamed about starting something on your own but didn’t know where to begin, you’ll see that even successful founders once stood exactly where you are. In this article, you won’t find polished success stories. This is where you’ll get to know how the leap from employee to founder truly feels like. I don't dare to take more of your time, so the first question is… What did the transition period look like for you?

Building with OpenAI, Gemini, or Groq directly is great for simple prototypes — but once your app grows, managing raw APIs quickly becomes a bottleneck. Different request bodies, different response formats, custom types, boilerplate everywhere… and switching providers becomes a headache. That’s exactly where LangChain changes the game Why Raw LLM APIs Hold You Back Here’s what developers run into when handling multiple providers manually: Every provider uses different request/response structures You constantly rewrite TypeScript interfaces Fetch wrappers, headers, parsing logic, error handling — repeated everywhere Switching models means updating half your code Scaling becomes harder when you add RAG, embeddings, agents, memory, etc. Great for “Hello world,” painful for real applications…  ( 7 min )

💡 Quick Take: The traditional full-stack roadmap is obsolete in the age of AI. To thrive, developers must adopt the 'Architect & The Automaton' model, focusing on system design and high-level direction while leveraging AI for implementation. The full-stack roadmap you've been memorizing is a map to a city that no longer exists. Learn HTML, then CSS, then JavaScript, then React, then Node.js, then a database, then Docker. It was a reliable, linear path. It created specialists in predictable stacks. That era is over. AI is not another framework to learn. It’s a tectonic shift that has fundamentally changed the landscape. Treating tools like GPT-4 or GitHub Copilot as mere productivity boosters is like seeing the first automobile and thinking, "What a nice, fast horse." You're missing the p…  ( 9 min )

Seeing Google's Doodle tribute to Pac-Man recently sent me spiraling down a nostalgia rabbit hole. It reminded me of a MOOC I took in what now feels like ancient history—a Gemini search of my old Gmail archives confirms it was UC Berkeley CS 188: Introduction to Artificial Intelligence via EdX, probably around 2012. The year 2012. The year Obama won re-election, the Mayan calendar "ended," and Honey Boo Boo was somehow a cultural phenomenon. Siri was barely a year old—helping sell iPhones like hotcakes despite rarely understanding what you asked. "Deep learning" was a phrase you'd find only in academic papers, not headlines. A different era entirely. That course required implementing classic algorithms like Greedy search and Minimax into Pac-Man. It was, honestly, a bit over my head at the…  ( 14 min )

Introduction Hello 👋, In this article I will present my opinions on Vibe Coding. In the last 2 years the term "AI Vibe Coding" has been very hyped. I mean the idea of "Clicking a button and generating anything you can imagine" is very exciting at first but not a great idea at the same time. I will give my opinion on why it isn't a good idea to depend on AI Vibe Coding tools. Let's first talk about how basically these Vibe Coding AI Models work. AI LLMs are trained on data and are trained to predict output from user input (prompt) based on that data. Which means AI Models that can code is trained on existing human written code and AI Models that can draw is trained on existing human drawn art. This means that AI can't create something entirely unique that has never been created by humans…  ( 8 min )

Hey everyone! AI-powered website security scanner designed to help developers and teams catch vulnerabilities before hackers do. It’s still early, rough around the edges, and absolutely an MVP… The MVP scans a website URL and uses AI + rule-based checks to flag: Common vulnerabilities (misconfigurations, exposed endpoints, weak headers) Potential security risks in publicly reachable pages Missing or unsafe security headers Basic performance & implementation issues that relate to security The idea is simple: give developers fast, actionable insights without needing to be a security expert. I’d love feedback from anyone in the dev → deploy pipeline: ✔️ Web developers ✔️ QA testers ✔️ Project managers ✔️ Security engineers / pentesters If you build or ship websites, this tool should feel immediately useful — or at least interesting enough to poke holes in. Security often becomes an afterthought — not because developers don’t care, Scanners are expensive OWASP tools feel intimidating Manual reviews are slow Teams don’t have dedicated security folks So the goal with this MVP is to make security checks accessible, fast, and AI-assisted. This is version 0.1 — tons of improvements planned: Deeper OWASP coverage Better AI reasoning (multiple agents) Exportable reports API access for CI/CD Scheduled scans Chrome extension for quick checks Team dashboards + history logs If enough devs find value here, I’ll double down on building it out. 👉 WebGuard Please break it.

Yesterday, I noticed something alarming in Mukbang 3D: regular users signing in with Google were being asked to grant access to Google Analytics data and Cloud Platform resources. For an app that just needs your email and name, this is terrible. Here's how a simple developer convenience created a confusing security prompt—and how I tracked it down. Instead of the clean, minimal consent screen users expect ("Mukbang 3D wants to access your email and profile"), they were seeing a wall of intimidating permissions including developer-level scopes like analytics.readonly. Understandably, users were abandoning the sign-in flow entirely. First I checked the mobile app's OAuth configuration. The Client ID looked correct—it only requested email and profile scopes.

The Paradox of Infinite Leverage We were promised a revolution. A suite of AI tools that would grant us 10x leverage, compress timelines, and unleash an unprecedented wave of creation. The tools arrived, yet the revolution feels… muted. Many find themselves busier than ever, caught in a frantic loop of prompt engineering, content generation, and tool-hopping. They are producing more noise, not more signal. This is the great paradox of the AI era: we have access to near-infinite leverage, yet our output remains stubbornly linear. Why? Because we are attempting to bolt a jet engine onto a horse-drawn carriage. We are applying 21st-century tools to 20th-century workflows and wondering why the system breaks.

Introduction When working with Uniface ProcScript, you might encounter mysterious syntax errors that seem to point at perfectly valid code. The culprit could be invisible non-breaking space characters (0xA0) lurking in your source files. This article explains the $ALLOW_NOBREAK_SPACE configuration parameter and how it can help you deal with this common issue. $ALLOW_NOBREAK_SPACE is a configuration parameter in Uniface 10.4 that controls whether non-breaking spaces (hexadecimal value 0xA0) are allowed in ProcScript code. By default, these characters cause syntax errors when the Uniface compiler encounters them. Syntax: $ALLOW_NOBREAK_SPACE = 1 | 0 Values: 1 - Non-breaking spaces (0xA0) are allowed in ProcScript 0 - Non-breaking spaces cause syntax errors Default: None (not set, be…  ( 7 min )

Introduction Recently, I read an article titled "Alias Settings of Engineers Around the World" (in Japanese). As a PostgreSQL engineer, this got me thinking: "If they are customizing their bash aliases, how are they configuring their psql environments?" Driven by curiosity, I decided to investigate GitHub repositories to see how developers commonly configure their psqlrc files. psql is the terminal-based front-end for PostgreSQL, allowing you to execute SQL interactively. Its configuration file is named psqlrc, and it has the following characteristics: System-wide settings: The system-wide psqlrc file is stored in ../etc/ relative to the directory containing the PostgreSQL executable. This directory can be explicitly set using the environment variable PGSYSCONFDIR. User-specific settings…  ( 22 min )

There has never been a stranger moment to be a Computer Science graduate. On one hand, the world is flooded with content telling you that “AI will replace programmers,” “coding is dead,” or “software jobs are disappearing.” On the other hand, every company—from scrappy startups to trillion-dollar giants—is aggressively announcing AI strategies, hiring AI engineers, looking for systems specialists, and expanding their technical teams. This contradiction has left an entire generation asking the same question: Where do I fit in? What exactly should I learn in a world where AI writes code, tests code, debugs code, and even architect systems? The answer isn’t that jobs are disappearing. The answer is that the bar has moved.

Breaking the Sound Barrier with AI: Reinventing Flight Design Imagine designing a supersonic jet engine without a wind tunnel, or optimizing a spacecraft’s heat shield before ever firing it up. The cost and complexity of physical testing have always been a massive bottleneck in aerospace engineering. But what if we could accurately simulate these complex aerodynamic conditions with unprecedented speed and efficiency using AI? The core idea is this: train a neural network to act as a "surrogate" for complex computational fluid dynamics (CFD) simulations. Instead of running computationally intensive calculations every time we tweak a design, we can use the AI to instantly predict the aerodynamic performance. This allows for rapid exploration of design possibilities, something previously im…  ( 7 min )

We spent the last two years figuring out how to make LLMs "smart." We learned RAG, Chain-of-Thought, and Tool Use. But in 2025, the challenge isn't intelligence. It's Containment. The difference between a demo and a production system isn't the prompt, it's the architecture that stops the LLM from bankrupting you or crashing your backend. I call this shift "Defensive AI Architecture." It's the discipline of treating LLMs not as magic oracles, but as non-deterministic, hostile microservices.

In the world of data management, querying databases efficiently and accurately is a common challenge. Traditionally, accessing information from databases requires knowledge of SQL, a skill that not all users possess. As businesses grow and data becomes more complex, multi-agent systems for text to SQL are emerging as a powerful solution. These systems enable users to interact with databases using natural language, converting text queries into SQL queries automatically. A multi-agent system is a collection of autonomous agents that work collaboratively to solve a complex problem. In the context of text-to-SQL, these agents specialize in different tasks, such as understanding the natural language query, mapping that query to the database schema, and generating the appropriate SQL query.

Software development is full of repeated problems — from creating objects to managing complexity to organizing code. Instead of reinventing the wheel every time, developers rely on design patterns — proven solutions that help keep code simple, flexible, and maintainable. Think of design patterns as reusable templates. They don’t give you exact code to copy-paste, but they guide you toward a clean and reliable way to solve common problems. Below are the patterns every developer should understand, no matter what language you work with. Sometimes you need a single, globally accessible object — like a database connection, logger, or configuration manager. Why it matters: Simple example: Creating objects can become messy when different types require different setup steps. The Factory Method pat…  ( 7 min )

Before Kiro, I saw AI as just another tool. After building Cadaver's Crypt, I see it as a development partner that understands context, domain knowledge, and creative vision. From: Linear coding with constant context switching To: Conversational development with integrated domain expertise Kiro didn't just help me write code - it helped me think through complex problems in medical education and find innovative solutions. When Kiro generated a complete Three.js anatomy viewer with built-in medical validation and Halloween effects in one conversation, I realized this was different. The platform understood: Medical accuracy requirements Educational psychology principles 3D graphics optimization Theme consistency needs The real value came from Kiro's ability to: Maintain context across multiple development sessions Suggest architectural improvements I hadn't considered Automate validation workflows that would have taken weeks Balance educational integrity with user engagement A production-ready medical education platform built in record time, with features that would typically require a full team of developers and medical experts. edtech #medtech #ai #webdev #innovation kiro  ( 6 min )

The Problem In our car mechanic CRM application, users needed to search across multiple entities simultaneously—customers, their vehicles, appointment history, and service records. However, our data architecture presented a significant challenge. Our application followed database normalization best practices. Data was organized into separate collections: Users collection - Customer information Appointments collection - Service appointment records Vehicles collection - Vehicle details with references to master data collections While this normalized structure kept our data clean and avoided redundancy, it created a performance bottleneck for search operations. To execute a single search query, we needed to perform 2-3 layers of lookups across collections, followed by text regexp searches. …  ( 9 min )

Waste management typically depends on fixed schedules. Drivers follow the same routine every day, even if bins are half-empty. This wastes time, fuel, and effort. GreenGuardian uses artificial intelligence to change this pattern by introducing dynamic waste monitoring and predictive planning. The system collects data from smart bins, drivers, resident requests, and historical waste patterns. AI models then analyze this information to detect waste hotspots, peak usage times, and unusual surges. This is especially useful during events like Bakra Eid, when organic waste increases sharply in certain areas. Route optimization is one of the key AI-powered features. Instead of sending drivers on predefined routes, the system creates routes based on actual bin fill levels, road layout, driver availability, and current workload. This reduces unnecessary travel, lowers emissions, and shortens collection time. Another intelligent feature is the sentiment analysis engine. Residents often express concerns or complaints through the mobile app. These messages are processed to understand their tone and categorize issues. This helps society administrators respond faster and identify repeated problems without manually reading every message. AI doesn’t replace human workers — it strengthens them. By giving accurate predictions, smarter planning, and meaningful insights, it allows staff to focus on execution rather than guesswork. As more data accumulates, the system continually improves its recommendations, making waste management smoother and more efficient over time.  ( 6 min )

We are thrilled to announce that echo3D now has a plugin for Autodesk 3ds Max. For decades, Autodesk 3ds Max has been the gold standard for 3D modeling, animation, and rendering. Now, by integrating directly with echo3D’s robust 3D Digital Asset Management (DAM) platform, we are closing the gap between creation and deployment. This integration allows 3D designers and teams at large organizations to stream 3D assets directly from the 3ds Max interface into the echo3D DAM, completely eliminating the friction of manual exports, uploads, and file juggling. Direct Streaming from Editor to Cloud The core of this integration is efficiency. Traditionally, moving a model from a design environment to a content delivery network involved a tedious cycle of exporting, optimizing, re-uploading, and v…  ( 7 min )

Three days before a customer pilot, our PM pinged me: "Can we ship that analytics dashboard?" The design had been sitting in Figma for weeks. I promised I'd have it in production by Friday with AI co-pilot. By Wednesday morning, the PR was still in draft. Not because the UI was hard—it looked exactly like the mock—but because the AI kept inventing work.

GitHub Home .env: A Grown-Up's Guide to Application Configuration 🧐 Let me tell you a ghost story. 👻 A few years ago, a new guy on our team made a mistake with a configuration item during an emergency online hotfix. He was supposed to point the database address to the read-only replica of the production environment, but he forgot to update that tiny .env file on the production server. The result? The live service connected to his local development database. 😬 The next hour was a disaster for our entire department. User data was contaminated by test scripts, order data was messed up, and the CEO's call went straight to my cell phone. We spent an entire weekend cleaning up data and appeasing users. And the root cause of all this was a single, tiny text file that someone forgot to modify…  ( 9 min )

In the previous part, we established that Babel is the "Translator." Now, let's see how this translator handles difficult situations in a real project. Many developers configure Aliases, run the app, and it works perfectly, but VS Code is covered in red errors. Or vice versa: VS Code is happy, but the app crashes. Why? Because this is the "Triangle of Synchronization." For an Alias (e.g., @components/Button) to work smoothly, three giant systems must shake hands: Babel: So the code runs (Runtime). TypeScript (tsconfig.json): So VS Code understands and provides autocomplete (Dev Experience). Metro: (Sometimes) To resolve overlapping imports.

So, quick backstory. I built this because my food kept getting cold. Most days I’d sit down with lunch, open a video site “just to find one thing to watch”, and then somehow I’d spend 15–20 minutes just scrolling. No video, food already not warm anymore, and my break was kind of gone. At some point I got annoyed enough that I opened my editor and started hacking. I ended up with this: 👉 Break Picks – a tiny site with hand-picked videos for short breaks https://break.baratheon.my.id/ No login, no feed, no “here’s 100 recommendations you didn’t ask for”. Just: a small list of videos I actually watched grouped by mood meant for break time, not “it’s 2AM how did I get here” time When I’m eating, I don’t really want to choose.

Introduction What started as a simple "let's optimize my development setup" turned into a complete infrastructure overhaul that would define my productivity for months to come. My development environment was becoming a bottleneck—port conflicts, slow builds, and tangled dependencies were slowing me down.

The Problem: Death by 1,000 Tabs Like many developers, my morning routine used to be a productivity killer. It involved opening about 25 tabs-Hacker News, TechCrunch, Bloomberg, various Substacks, Twitter-trying to find the actual "signal" amidst the noise. The reality? 90% of it was repetitive clickbait or shallow press releases. I realized I was spending an hour just trying to find something to read, rather than actually reading. I decided to engineer my way out of this loop. I didn't just want a GPT wrapper that summarizes text. I wanted an autonomous system that could research, cross-reference multiple sources, write a draft, and then-crucially-critique its own work before showing it to me. Here is how I built TrendFlow, an agentic news workflow using Python, LangGraph, and Google Ge…  ( 8 min )

It’s impossible to ignore the moment you realize your entire recommendation hinges on a diagram your client doesn’t fully understand. That single misunderstanding can derail timelines, dilute insights, and slow decision-making. Many consultants struggle with diagram clarity, especially when trying to simplify layered systems, competing priorities, or complex workflows. These challenges quietly drain hours and create unnecessary friction across business consulting workflows, leaving teams stuck re-explaining instead of moving forward. Why Documentation Inefficiency Keeps Projects From Gaining Momentum Nothing stalls a project faster than documentation that feels scattered, outdated, or overly dense.

Terraform is one of the most popular Infrastructure as Code (IaC) tools used by DevOps engineers. While Terraform Core is responsible for managing configurations and state, providers are the plugins that allow Terraform to interact with cloud platforms, SaaS services, and APIs. In this post, we’ll explore Terraform providers, why versioning matters, and how to manage provider versions effectively. Terraform Providers are plugins that act as a bridge between Terraform and your cloud infrastructure or services. Example: To create an AWS EC2 instance or S3 bucket, you use the hashicorp/aws provider. Think of Terraform Core as the brain and Providers as the hands that manipulate resources in the cloud.

Two poems about burnout, growth, and the dreams we cultivate when the terminal goes dark. I've been in tech for five years now. Not long enough to call myself a senior, but long enough to have worked alongside brilliant engineers who've been doing this for a decade or more. And you know what I've noticed? That faraway look in their eyes during sprint planning. That wistful tone when someone mentions "work-life balance" like it's a mythical creature. These poems aren't born from my own ten years of experience - I'm not there yet. They're born from watching the people who mentored me, the ones who taught me everything from Git workflows to handling production incidents at 2 AM. They're born from the stories they've shared, the exhaustion I've witnessed, and the surprising number of senior en…  ( 8 min )

By Muhammed Shafin P (@hejhdiss) Licensed under Creative Commons Attribution-ShareAlike 4.0 International License (CC BY-SA 4.0) As I explained in my previous article, Qeltrix V1 through V5 aren't five different tools—they're five incremental proofs-of-concept demonstrating different aspects of a single, unified cryptographic archiving system. Think of them as chapters in a book, not different books entirely. V6 represents the next chapter in this ongoing story: network-native streaming.

I remember the day clearly. After returning from KubeCon in 2022, I was curious about local AWS activity and decided to search for user groups near me. I found a meetup listed for Vadodara and went — not as a speaker, not as an organiser, simply as someone who wanted to learn. Walking into that room for the first time was a small shock. People were talking architecture, deployments, and product announcements like it was just another day. I felt out of place for a moment. Then Manan Vasavada — hosting the meetup at Avdevs — said something simple and disarming: “No one here is an expert. You have a topic? Just talk about it.” That sentence changed everything. It removed the need to be perfect. It made space for people who were curious and willing to share. I kept coming back. My first AWS Us…  ( 11 min )

AI code generators write more code than ever, and they do it fast. Sahil Lavingia said it well in a recent tweet. If developers now produce five to ten times more code with AI, we need something that can review five to ten times more code too. That is the real problem. Tools like Cursor generate code that looks right but often contains small mistakes that only show up when the project runs. Wrong Prisma fields, missing checks, loose validation, repeated logic, or scripts that fail silently. None of this feels dramatic. It is just enough to slow you down or break production. I hit all of this while building an Express TypeScript API. Cursor helped me create the project fast, then I spent real time fixing the parts it got wrong. That is when the pattern became clear.

GitHub Home I still vividly remember that Friday midnight. I, a man in my forties who should have been at home enjoying the weekend, was instead in a cold server room, the hum of fans buzzing in my ears, and a stream of error logs scrolling endlessly on the terminal before me. What was supposed to be a "simple" version update had turned into a disaster. The service wouldn't start, the rollback script failed, and on the other end of the phone was the furious roar of a client. At that moment, staring at the screen, I had only one thought: "There has to be a better way." We old-timers grew up in an era when the term "maintenance window" was a fact of life.

Note: This article contains affiliate links. I only recommend hardware I actually use. If you are a student starting your cybersecurity journey, you have probably Googled “Best WiFi Adapter for Kali Linux.” And you probably saw thousands of old forum posts recommending the TP-Link TL-WN722N. Do not buy it. Here is the trap that catches 90% of beginners: Version 1 of that adapter was legendary. It used the Atheros AR9271 chipset. Version 2 and Version 3 (which is what Amazon sells now) swapped the chipset to the Realtek RTL8188EUS. Why does this matter? does not support Monitor Mode or Packet Injection native to Linux. If you buy it, you will spend 3 days fighting with GitHub driver patches, kernel crashes, and errors. It is a nightmare. I stopped fighting with old adapters and switched to the Alfa AWUS036ACS. After testing it for a month, here is why it is the only budget adapter I recommend for students: It runs on the Realtek RTL8811AU chipset. Unlike the TP-Link, the drivers for this are stable in the Kali Linux repository. You install them once, and it works forever: sudo apt install realtek-rtl88xxau-dkms Old adapters (like the Alfa NHA) are single-band (2.4GHz only). 5GHz (AC). It usually costs around $25 — $30. Stop trying to make the TP-Link work. It’s not 2016 anymore. If you want to plug it in, run airmon-ng, and start capturing handshakes immediately, get the Alfa.

Question 1: You have launched an EC2 instance that will host a NodeJS application. After installing all the required software and configured your application, you noted down the EC2 instance public IPv4 so you can access it. Then, you stopped and then started your EC2 instance to complete the application configuration. After restart, you can't access the EC2 instance, and you found that the EC2 instance public IPv4 has been changed. What should you do to assign a fixed public IPv4 to your EC2 instance?

Large Language Models (LLMs) like Claude possess incredible reasoning capabilities, but they suffer from a critical flaw: They have no object permanence. Once you close a chat session, the "mind" is wiped. While features like "Projects" or huge context windows (200k+ tokens) help, they are temporary buffers, not true memory. They are expensive, slow to re-process, and don't persist across different interfaces (e.g., moving from VS Code to the web interface). To move from Chatbots to true Agents, we need to solve the state problem. The Model Context Protocol (MCP) is often described as a way to "connect AI to tools." But theoretically, it allows us to decouple the reasoning engine (the LLM) from the state (the data). Instead of trying to cram everything into the prompt (Context Stuffing), w…  ( 10 min )

"So you work like hell just to make sure that you do everything you can to get your guys prepared. ... And our guys really captured the moment and played great After a shaky start, which gave Michigan an early 6-0 lead, the Buckeyes dominated in every facet the rest of the way.  ( 6 min )

AI-driven search engines are rapidly replacing traditional keyword-based discovery. Instead of scrolling through multiple pages of results, users now rely on intelligent assistants such as ChatGPT, Gemini, Microsoft Copilot, and Perplexity to deliver instant, conversational recommendations.

Escribo herramientas para no hacer las cosas aburridas dos veces, y últimamente lo he estado haciendo en lenguajes que nadie espera. Esta vez: Julia. Sí, ese lenguaje científico que todos asocian con matemáticas y machine learning. Si alguien está en desacuerdo solo grite. Hace un par de semanas me di cuenta de algo: uso como 51 contraseñas diferentes (ok, son más), las guardo en un gestor comercial, y no tengo ni idea de qué tan "fuertes" son realmente. Así que decidí construir mi propio gestor de contraseñas que no solo almacene credenciales, sino que también me enseñe qué hace a una contraseña verdaderamente segura.

This article is Chapter 3 of the Free Java Course. It was originally published on SRF Developer. You cannot write a single line of Java code without the JDK (Java Development Kit). Many beginners get stuck right here. They download "Java," try to run a command, and get the dreaded error: 'javac' is not recognized as an internal or external command. In this guide, I will walk you through the correct way to set up your environment for Windows, Mac, and Linux, and how to fix the Environment Variable issues. Before we install, you need to download the right thing. JRE (Java Runtime Environment): Lets you run Java apps (like Minecraft). JDK (Java Development Kit): Lets you write and compile Java apps.

Today we're going to take a swing at translating a Great Expectations Python script into CsvPath Framework. The script comes from the GE documentation site. First a bit about the tools. Great Expectations is a data quality tool for live production pipeline data checking. You know, the thing we all know we should be doing but mostly aren't. GE comes as a core expectations library and a paid SaaS service that adds teamwork and visualization. The expectations are essentially data quality rules realized in Python functions. Each function contains the logic of the test and the hooks for it to work within the framework's larger context. Like CsvPath Framework, GE brings together data sources, data rules, and context to generate metadata. However, Great Expectations is a quality control toolkit,…  ( 12 min )

I Built an AI Interview Coach That Runs Entirely in Your Browser (No API Keys Required!) TL;DR: I created a free, privacy-first interview prep app that uses AI to generate questions and provide feedback—all running locally in your browser. No servers, no API keys, no data collection.

Hey Indie Hackers 👋 It’s called pngtowebp.io, and it converts PNG images into WebP directly in the browser. No uploads, no accounts, no nonsense. Why I built it PNG files were slowing everything down. Lighthouse kept yelling at me. I know the solution was WebP, but most tools online were: Too slow Full of ads Required uploading files Hidden behind paywalls Or had weird usage limits I just wanted something fast, free, and private. So I built it myself. What the tool actually does Not much, honestly — and that’s the whole point. You upload PNG → it gives you WebP. The entire conversion happens locally in your browser, using: His tool is very easy to use — you just need to upload your PNG file, and it will generate a WebP file for you. It’s extremely fast and convenient. pngtowebp.io If you use it and something breaks, or if you have an idea to make it better, I’d genuinely love to hear from you.

Interface compliance checks in Go let you verify at compile-time that your types actually implement the interfaces they claim to, preventing runtime disasters. By adding a simple declaration like var _ http.Handler = (*Handler)(nil), you force the compiler to verify your implementation before your code ever runs—catching bugs in seconds instead of hours. There I was, feeling like a 10x developer. I'd just refactored our HTTP handler system. Clean code. Beautiful abstractions. Chef's kiss. I hit deploy and closed my laptop. Weekend mode: activated. PING PING PING My phone lit up like a Christmas tree. Production was down. Users were getting 500 errors. My handler wasn't... handling.

It's November 2025, which means finance wants your Q1 2026 budget by yesterday, and you're staring at a spreadsheet that somehow spent $180,000 on "digital marketing" with the specificity of a fortune cookie. Here's the thing: most marketing teams aren't bad at budgeting because they're careless. They're bad at it because they're optimistic. That Facebook campaign that "performed well"? Define well. That content initiative that "built brand awareness"? Cool, cool—how much brand awareness costs per unit, exactly? I've audited enough marketing budgets to know the pattern. Roughly 20-30% of annual spend goes to things that either don't work anymore, never worked, or nobody can actually remember approving.

Originally published on Entropic Drift Over the past few weeks, I've been migrating Prodigy—my Rust-based AI workflow orchestration tool—to use functional programming patterns from Stillwater, a library I built for applicative validation and effect handling in Rust. The migration touched variable aggregation, environment access, and workflow execution. Not every change was revolutionary, but three patterns produced outsized benefits in testability, safety, and code clarity. This post breaks down each one with concrete before/after comparisons. The Problem: Prodigy's MapReduce workflows aggregate results from parallel AI agents.

Pre-compiled Neovim binaries fail on OpenWrt with interpreter/linker errors: ei https://github.com/neovim/neovim/releases/download/nightly/nvim-linux-x86_64.tar.gz nvim # Error: Failed to execute process: The file exists and is executable. # Check the interpreter or linker? This happens due to glibc/musl incompatibility. Building from source ensures compatibility with OpenWrt's musl libc. This guide uses OpenWrt 24.10.4 x86_64. For other versions, refer to the original guide. Install the required build tools and libraries: opkg update opkg install git git-http python3 python3-pip make luajit gcc coreutils-install pip install cmake OpenWrt's minimal environment lacks some standard libraries that Neovim expects. The dynamic linker library is built into musl but needs a stub for linking: printf "!\n" > /usr/lib/libdl.a This creates an empty archive that satisfies the linker without adding actual code (musl already provides dlopen and friends). Create a dummy shared library for the utility functions: echo "int main() { return 0; }" > dummy.c gcc -shared -o /usr/lib/libutil.so dummy.c rm dummy.c Most libutil functions (like forkpty) are either unused by Neovim or provided by other libraries on musl systems. Clone the repository (shallow clone to save space): git clone https://github.com/neovim/neovim --depth=1 cd neovim Build with release optimizations and debug symbols: make CMAKE_BUILD_TYPE=RelWithDebInfo This takes 10-30 minutes depending on your system. The RelWithDebInfo build type provides good performance while keeping some debug information for troubleshooting. Install to the default location: make install This installs to /usr/local/bin/nvim. Create a symlink for convenience: ln -sf /usr/local/bin/nvim /usr/bin/nvim Verify the installation: nvim --version LazyVim is a modern Neovim configuration with sensible defaults and a plugin manager. git clone https://github.com/LazyVim/starter --depth=1 ~/.config/nvim On first launch, Neovim will automatically install plugins: nvim opkg install tmux  ( 7 min )

GitHub Home A hacker exploited this vulnerability, bypassed authentication, and stole the entire user table data. By the time we discovered it, it was too late. For the next few months, our entire team lived in nightmares: cooperating with investigations, appeasing clients, fixing vulnerabilities, checking all company projects for similar risks... The company's reputation and business suffered heavy damage. That incident taught me the most profound lesson: in the world of web development, security always comes first. Many developers, especially when project deadlines are tight, view "security" as a "feature module." They say: "Let's implement the main functionality first, and we'll 'add' security features in the next iteration." This is a fatal misunderstanding. Security is not a coat of p…  ( 9 min )

Let’s be honest, most insurance software looks like it was built when Nokia phones were “cutting edge.” Guidewire saw this too. Enter JDP — the Jutro Digital Platform. A framework? Yes.

Introduction: The Shift in Audio Engineering The domain of digital signal processing (DSP) has historically presented significant barriers to entry. Tasks such as isolating a specific instrument from a mixed audio file were once considered technically impossible—often compared to "unbaking a cake" to retrieve the eggs and flour. However, the advent of machine learning models trained on spectral data has fundamentally altered this landscape. Before discussing the workflow, it is essential to understand the technology behind "unmixing." Modern source separation relies on deep neural networks (DNNs) that analyze the spectrogram of an audio file. These networks are trained to recognize the specific frequency footprints and harmonic structures of different sound sources. The first application…  ( 8 min )

(For individual use, please see GPTLocalhost.) Recent findings show that 77% of workers disclose confidential business information via ChatGPT and other cloud AI platforms, posing significant security and compliance challenges. Given Microsoft Word’s status as a widely used word processor, it’s not surprising that some workers might transfer sensitive information to these external AI services by copying and pasting. In light of these concerns, organizations are increasingly turning to on-premise Large Language Models (LLMs) to safeguard sensitive data and ensure regulatory compliance. By hosting LLMs internally, businesses can exert greater control over their information environments, reducing the risk of unauthorized access or data breaches associated with external cloud services. For legal professionals, the implications of these findings are particularly significant. Addressing security concerns, they now have an effective solution available: the IBM Granite 4 series models for contract analysis seamlessly integrated into Microsoft Word. This integration is enabled through a local Word Add-in named LocPilot, which brings local LLMs to Microsoft Word. With LocPilot, your team can run powerful LLMs directly on their computers or an Intranet server — eliminating the need for cloud services and monthly fees while ensuring complete privacy. You can effortlessly switch between models and work more efficiently, all within a local environment. Here’s a quick demo: We hope this demonstration opens up new avenues for thought and inspires you to develop additional use cases that empower your team with the latest on-premise AI. If you have any specific ideas or suggestions, please don’t hesitate to contact us at info@locpilot.com. Our mission is to make local AI more accessible and affordable for all teams.  ( 7 min )

In my previous blog post, I covered the fundamentals of PL/SQL collections, focusing on the different types: Associative Arrays, Nested Tables, and VARRAYs. While there’s much more to explore about collections, in this post, I’ll focus on two important collection methods: DELETE and TRIM. Collection Methods They are called methods because they use member method syntax, unlike functions or procedures, which require passing collections as parameters. The syntax is similar to other programming languages, such as JavaScript. For example: COUNT function: Returns the current number of elements in a collection. Wrong Syntax COUNT(book_table) Correct syntax book_table.COUNT Note that collection methods are available only in PL/SQL, not within SQL. While I’m not listing and explaining all the collection methods, let’s focus on DELETE and TRIM, as they have interesting behaviors we should know. DELETE Method DELETE (without any arguments) DELETE(i) Removes the i-th element from a nested table or associative array. DELTE(i, j) Removes all elements in an inclusive range starting from i and ending at j. Important Note: When you use parameters with DELETE, a placeholder is kept for the “removed” element. TRIM Method Do Not Use DELETE and TRIM on the Same Collection PL/SQL offers powerful and useful methods, but it’s important to pay close attention to how each one is used.  ( 7 min )

The world of software delivery has changed forever. Gone are the days of isolated dev and ops teams exchanging endless tickets. Now, speed, collaboration, and automation rule. At the center of this evolution stands DevOps — a movement reshaping how software is built, tested, and deployed. Imagine this: your development team pushes new code at 10 a.m., automated tests validate the changes, infrastructure scales dynamically, and within minutes, users see the update. That’s the kind of magic DevOps enables — powered by the right tools. Let’s embark on a practical tour through 20 essential DevOps tools every modern organization should know. Jenkins remains the heartbeat of continuous integration and delivery. It automates building, testing, and deploying code so developers can focus on innov…  ( 9 min )

Background Current Business Retreats Are you familiar with business retreats? These are intensive study camps or employee trips with a focus on relaxation, organized for companies operating primarily in a near-full remote work mode. Typically held about once every six months, they target companies that allow remote work, especially tech companies. The specific way a retreat is conducted varies from organization to organization, but one common aspect is that members must always spend time together. Usually, some curriculum is planned, and everyone gathers in a room for workshops, or even during free time, there is pressure to interact, converse, and engage in discussions with other members. Certainly, such an environment allows for refreshing, temporarily disconnecting from wor…  ( 9 min )

Unlocking AI's Universal Secrets: Do Neural Networks Think in Fractals? Imagine training an AI to recognize cats. It excels with close-up photos, but fails miserably when shown a distant, pixelated feline. This exposes a fundamental challenge: how can we build AI systems that generalize across different scales and perspectives? The answer might lie in a hidden mathematical structure spontaneously emerging within neural networks: Kolmogorov-Arnold Geometry. At its core, Kolmogorov-Arnold Geometry describes a way to represent complex functions as compositions of simpler functions. Think of it like breaking down a complicated painting into a series of simpler brushstrokes at different magnifications. The fascinating discovery is that neural networks seem to learn this geometric structure on…  ( 7 min )

For years, tech leaders have repeated the same line: “Data is the new oil.” And they’re right, data powers AI the way oil powered the industrial revolution. But here’s what almost nobody is talking about: If data is the new oil, prompting is the new pipeline. Because without the right pipeline, the oil is useless. AI isn’t just about having the data. And prompting is the system that makes that possible. Let me explain why the future of AI belongs not just to those who have data… but to those who know how to speak to intelligence. 1. Prompting Turns Raw Intelligence Into Usable Output A model is like an engine. But without a transmission system, the power goes nowhere. Prompting is that transmission system.

I recently baked a football cake and it helped me realize AI agents work just like layered desserts. Here’s how flavors, molds and icing maps to agentic design. The code example below is designed to break down user goals into actionable steps and execute them using either custom tools or LLM reasoning. It uses regex to extract numbered steps from the LLM’s plan output. Executes each step by matching keywords like "search" or "compute" to the appropriate tool, or falls back to LLM reasoning. Just like a custom cake has layers of flavor, structure, and decoration, an AI agent has its own stack. It uses llama 3 LLM model and created two custom simple tools: search_tool() - simulates a search engine returning mock results. compute_tool() - simulates a computation task returning a placeholder…  ( 11 min )

It’s mathematical teleportation. A secret told only to yourself = a unary key (private universe) A secret told BETWEEN identities = a binary key (shared universe) And the moment we said: secret “secret@withwhom” We invented the algebraic rule for shared secret derivation. Unary vs Binary Secrets Unary secret (private channel) me.wallet.secret("alpha") This produces a 1-arity universe: U(alpha) → only ME can derive it Because the keyspace derives only from: secret + path + local identity So only you can decrypt the blob under: 🔗 2. Binary secret = shared universe me.wallet.secret("alpha@pamela") This is fundamentally: U(alpha@pamela) = intersection( ME_identity , Pamela_identity ) A 2-identity shared space. So: It creates what cryptographers call: A Multi-party Semantic Channel.  ( 6 min )

I did the thing every developer dreams of: I built and launched my own SaaS product, PostPulsar (https://post-pulsar.com). It’s a tool I'm genuinely proud of—it uses AI to help content creators like me save hours by repurposing blog posts into social media content. Then came the hard part. The part they don't always talk about in the success stories. Marketing. As a developer, my first instinct is to solve problems with code, not with marketing campaigns. And my second problem is a bit more specific: I'm based in Brazil. I quickly ran into two massive walls. Wall #1: The Time Sink Like many of you, I'd rather spend my time improving my product than trying to keep up with five different social media platforms. I actually built PostPulsar to solve my own problem of not having enough time for…  ( 7 min )

“You should live your life like a lion which means that most of your time you’re resting, lazing around, doing whatever you find entertaining, and then once in a while, you get obsessed with something and you just pour everything into it.” - Naval Ravikant Last year, I completed my Masters in Australia. Two paths lay ahead: accept a comfortable job with visa security, or build something that could create real impact. This philosophy captured my journey with Nexus Beings. For a long time, the concept lived quietly in notes and sketches while I navigated life as an international student. Then came the obsession: building digital agents that don't just respond, but understand; systems that bring context, emotion, and intent to the world of service. I chose to build. Today, Nexus Beings has achieved proof of concept. Bootstrapping as an immigrant meant every decision carried extra weight. Without external funding or a safety net, every line of code, every experiment, and every pivot had to matter. These constraints became my greatest teacher, fostering innovation through limitation and patience through uncertainty. This milestone represents more than technical validation. It proves that conviction outlasts complexity and that clarity of purpose sustains when traditional resources cannot. While Nexus Beings continues to evolve, our foundation stands strong: intelligent real-time conversational video agents that deliver warmth, reliability, and empathy to service environments. What began as an experiment is steadily advancing toward redefining digital presence in customer experience. The comfortable job would have been easier. But building technology that transforms how businesses connect with customers? That obsession was worth every risk. The journey continues, grounded in purpose and guided by the belief in what's next.  ( 8 min )

Achieving this relies on two critical elements: a cleverly design…  ( 7 min )

Faith that unlocks righteousness. Romans 4 is not just Paul teaching theology. It’s Paul pulling back the veil on how God has always worked with humanity. Long before Scripture developed its structure, long before Israel became a nation, long before there was a temple, a priesthood, or religious tradition, God revealed something far more foundational: Righteousness has always been a matter of the heart. Everything else is commentary. In Romans 4, Paul is not introducing a new idea—he’s reminding the church of something ancient, something older than Moses, older than Jacob, older even than circumcision: the righteousness that comes through believing God simply because He said so. Today, we’re going to walk deeply through this chapter, line by line and theme by theme, until the weight of it …  ( 14 min )

Okay, let’s talk about something that’s been buzzing in the tech world lately: vibe coding. If you’re scratching your head wondering what that even means, don’t worry—I was too when I first heard the term.

So, grab a coffee, and let’s unpack what vibe coding is, why it’s making waves, and what it means for the future of coding. Picture this: instead of meticulously typing out every line of code, sweating over syntax, and debugging for hours, you’re describing what you want your program to do in plain English (or, you know, whatever language you vibe with). You’re not fussing over semicolons or curly braces—you’re just laying out the vibe of what you’re trying to build. Maybe you…  ( 10 min )

Hybrid cloud security was built before the current era of automated, machine-based cyberattacks that take just milliseconds to execute and minutes to deliver devastating impacts to infrastructure. The architectures and tech stacks every enterprise depends on, from batch-based detection to siloed tools to 15-minute response windows, stood a better chance of defending against attackers moving at human speed. But in a weaponized AI world, those approaches to analyzing threat data don't make sense. The latest survey numbers tell the story. More than half (55%) of organizations suffered cloud breaches in the past year. That’s a 17-point spike, according to Gigamon's 2025 Hybrid Cloud Security Survey. Nearly half of the enterprises polled said their security tools missed the attack entirely. W…

Enterprises are investing billions of dollars in AI agents and infrastructure to transform business processes. However, we are seeing limited success in real-world applications, often due to the inability of agents to truly understand business data, policies and processes. While we manage the integrations well with technologies like API management, model context protocol (MCP) and others, having agents truly understand the “meaning” of data in the context of a given businesis a different story. Enterprise data is mostly siloed into disparate systems in structured and unstructured forms and needs to be analyzed with a domain-specific business lens.s As an example, the term “customer” may refer to a different group of people in a Sales CRM system, compared to a finance system which may use …
